How to Throw an Under the Sea Party
Before you start coming up with ideas for your Under the Sea party, you’ll need to have a plan! Follow these simple steps for throwing a fun ocean themed party, no matter where you live.
Pick a location. Just because you’re throwing an ocean party doesn’t mean your party has to be at the beach! If you’re like me and live no where near the ocean, try hosting your under the sea party at one of these fun locations:
- At home. You can create an amazing ocean themed party at home! Set up a luau or beach BBQ in your backyard by adding fun decorations and serving cute food.
- At the pool. Take your party to your local pool so your kids can have some fun in the water without the need for messy sand.
- Near a lake. You don’t need the ocean when you have a lake nearby. Create an under the sea themed party on the shores of your favorite lake instead.
- Aquarium. Enjoy sea life from indoors by booking your party at a nearby aquarium.
Invite your friends. Send out some cute ocean themed invitations to all your guests to make sure everyone knows about your party!
Decorate the space. You can’t have an under the sea party without decorations! Find fun ocean-themed decorations at Dollar Tree or Amazon, then set up an amazing sea-inspired party in any location you choose.
Make cute food. Find some fun ocean themed party food ideas, then whip up a few cute recipes to serve your guests at your party. You can create themed food for your celebration or make an ocean themed menu, like luau or seafood.
Entertain your guests. Once the party has started, you’ll need to keep your guests entertained. Under the Sea party games are perfect for parties with guests of all ages. And if you have little ones coming to your celebration, making ocean themed crafts is a great idea!
Thank your guests for coming. After your party is over, make sure you tell all your guests thanks for coming with goody bags. Fill your bags with cute under the sea party favors for your guests to enjoy when they get home.
