If you’ve got a little one who’s never seen the Little Mermaid in theaters, why not treat them to a theatrical experience for their birthday?

Try renting a Peerspace venue with a home theater and watching the movie on the big screen. Older guests can enjoy the nostalgia factor, and younger guests can enjoy the movie in a whole new way.

Want a chance to express your inner mermaid style? Then you’re going to love this Little Mermaid party idea. Ask your guests to come in their best mermaid-inspired attire for your party.

You can ask guests to put their spins on Ariel’s outfit for a Disneybound-Esque outfit or have them create more abstract takes of what a mermaid might wear on the land. It’s an excellent opportunity for guests to flex their creative muscles. 

6. Beachside mermaid party

Instead of heading under the sea for your Little Mermaid party, why not do the next best thing and host next to the sea? If you’re lucky enough to live by the ocean, hosting your party at the beach can help you set the stage for a day full of mermaid-inspired fun.

If you need a “home base” to set up your mermaid party supplies, keep an eye out for rentable Peerspace beach houses like this Del Ray beach house in LA.

Not lucky enough to live by the sea? The pool is the next best thing! Pools can provide a perfect backdrop for a day of splashy mermaid fun with friends.

You can easily find rentable pools designed with parties in mind on Peerspace, like this beachy pool in Westside LA. It’s one of our favorite Little Mermaid pool party ideas for summer birthdays. 

8. Freshwater Mermaid party

Who says mermaids only live in the sea? If you’re not lucky enough to live by the coast, try hosting your little mermaid party by a lake or river. You’ll enjoy a water feature at your mermaid party and some freshwater mermaid fun on a special day.

If you need help finding an awesome spot, keep an eye out for Peerspace homes near water, like this colorful modern home in Silverlake, LA

9. Mermaid spa day

Want to spend the day relaxing mermaid style? This Little Mermaid party idea is for you. Host a mermaid spa day and kick your tail back for a little undersea-style pampering. Getting mani-pedis would be an excellent way to keep the mermaid theme going, especially with Little Mermaid-inspired colors or designs. 

10. Mermaid makeovers

Instead of a spa day, why not host a mermaid-themed makeover party where guests can bring out their inner mermaid? Grab your eyeshadow palettes and fire up the Youtube tutorials, then try to recreate your favorite mermaid-inspired looks IRL.

It’s a fun opportunity for younger guests to play with makeup and express their unique sense of style.
