Check out Peerspace for some highly original venues where you can host an unforgettable eighteenth birthday party. In fact, you could have friends over at this New York City “funzone lounge” that can accommodate 25 guests. It comes complete with table games, karaoke, and a place to set out (non-alcoholic) beverages and pizza.

However, if you’re in the Bay Area and you’re feeling glamorous, you might book this ninth-floor San Francisco luxury apartment (pictured above) with amazing city views and tons of light.

And the Peerspace Concierge service is available to source and deliver anything else you need, including equipment and catering. There are thousands of similar, reasonably priced venues available to book in cities all over the US, Canada, and Europe, where you can host a truly unforgettable party for your 18-year-old.

2. Mocktails, anyone?

Alcohol is still a definite no-no for American teens at age 18. Remind them that they don’t need alcohol to celebrate a birthday and host a mocktail-making party! This is a fun way to get everyone together and make something tasty to sip during the party. Mocktails are heavy on fruit juice and seltzer, so variety is key to ensure there is an option for every taste. Search Pinterest and TikTok for mocktail recipes that will delight your teen and their friends.

You can also opt to book a charming Peerspace venue that has plenty of countertop space for all the mocktail-making hijinx. And if you’d rather leave it all to the professionals, ask the Concierge service to send over a professional bartender who’s excited about the prospect of making mocktails for the young crowd.

3. Host a drive-in shindig

Rent a projector and a giant inflatable movie screen and show a couple of the birthday person’s favorite films. Invite all their friends and family, tell them to bring blankets or other seating, and walk around serving popcorn, soda, and maybe some finger food. Don’t forget to provide a cake! You could even embarrass the guest of honor by projecting some of their baby photos.

If you don’t have enough space available, book a Peerspace home with a big backyard or an indoor private movie theater.

For instance, you can book this drive-in movie theater in Santa Monica (pictured above) that is 60,000 square foot outdoor space and just steps away from the Santa Monica Pier. This is one of those 18th birthday party ideas that are fun year-round and that create lasting memories.

4. Throw a sleepover

Now that the birthday kid is technically an adult, host a co-ed sleepover which no doubt would have been illicit before this big milestone date. Show horror films, eat junk food, and play those fun sleepover games that everyone with actual responsibilities looks back on longingly. It will thrill the guests to keep one toe in childhood before being pushed out into the big, scary world of being a grownup.

Want to host this one outside the home? We get it! Why not book a totally amazing glamping space for your teen and their friends? And of course, you can do so with ease through Peerspace. Here are a few of our favorite spaces to get you started:

5. Personalized party

Is the newly 18-year-old into cooking fine food? Host a collaborative dinner party with their friends and family. Do they like making music? Why not have an old-fashioned singalong with or without a karaoke machine? Maybe they’re a fan of magic. If so, hire a magician!

Such a highly personalized event will let them know that they are truly loved and heard. They will forever look back on it fondly at this unforgettable 18th birthday party idea.

6. Have an in-home makeover event

If the birthday guest of honor is interested in shopping and/or makeovers, hire stylists to come to the party and do the guests’ hair and makeup. Partygoers (or in this case, their parents) are expected to purchase items from these services, so let the guest of honor select their own birthday gifts from the smorgasbord of fabulous temptations.

Nationwide examples of these services are Glam Squad and Pamper Party, but if they’re not available in your area, just do an internet search for in-home makeover party services. Alternatively, you could always have an in-home spa party with homemade or store-bought facial masks, colorful pedicures, or whatever would make the birthday person happiest.

7. Retro roller skating

When was the last time your 18-year-old went roller skating? Probably too long ago. Rent out or just take over your local rink and host an unforgettable eighteenth birthday party under the colorful lights. Skate to the sound of the greatest disco hits of all time. Shoot the duck, play limbo, and enjoy a corndog or slushy at the snack bar.

Let the DJ know that there’s a birthday in the house, and they’re sure to play the guest of honor’s favorite song. Again, don’t forget to bring a cake, because that’s one of those 18th birthday party ideas that fits everywhere!

8. Take a birthday vacay

If it’s in the budget, invite the newly minted 18-year-old’s besties and family members on a getaway. The birthday person could choose a carpool day trip party to a state park for a picnic, a week-long bash at a people-pleasing destination like Disneyland, or a day sprawling on a sandy beach. Heading out of town with friends and family is an 18th birthday party idea that they won’t soon forget.

Opt to rent a luxury home on Peerspace that will make it feel like a birthday vacay retreat for everyone invited.

9. Get crafty

It’s always fun to get together and make stuff, so another idea for an unforgettable eighteenth birthday party is to host a crafting party. Crafting parties can take place at your home or at a local venue, like a paint-your-own-pottery boutique. Guests can make anything from beaded jewelry to paint-by-number posters, learn to knit, or tie-dye some team birthday shirts.

If you’re short on ideas, consider this list of adult craft party ideas.

10. Mighty mysterious dinner

Wannabe detectives of all ages love a good murder mystery, especially when it doubles as a birthday dinner party. While you can invent your own clandestine narrative setup, you can also find prepackaged thematic mystery party games online.

Simply answer the questions about how many guests will be attending, download and (sometimes) print the materials, and pay for the package. Voila! You’ve cracked the code of how to host an unforgettable 18th birthday party.

You can even rent a castle on Peerspace and play the murder mystery within its eccentric walls!

Our how to host a murder mystery party post offers all the tips and tricks you need to pull off this idea brilliantly!

11. Dessert potluck

If sweets are your teen’s jam, host a collective dessert party. Everyone brings a cake, cookies, soda, pie, and other tempting treats of their choosing, so you can all enter a sugar coma together. What a way to ring in adulthood! Your 18-year-old will thank you sweetly.

If you host your event at a Peerspace venue, you can even book a private event at a local ice cream or dessert shop. That way, all you, the birthday person, and your guests have to do is show up and eat!
