Mermaid Birthday Party in Orange County

The Signature Mermaid Party

An all-inclusive private birthday party at Once Upon an Island on Balboa Island in Newport Beach, California. She arrives as a girl and leaves as a mermaid. That is the whole promise of the Signature Mermaid Party, and everything in the room is built to keep it: a hand-built lagoon with a waterfall, a rainbow tunnel she walks through to reach it, a salon under a glowing jellyfish canopy, and a clamshell throne waiting for the moment she puts on her tail.

Picture the day

This is how the party runs.

Four Neverland Mermaids host it from the first bubble to the last cup of tea. Here is the whole thing, in order, so you know exactly what you are booking.

Exclusive full private venue rental included with the Signature Mermaid Party

1It starts

She swims through the rainbow.

The doors open and she does not walk in, she swims through: through the rainbow tunnel and out into a sea of bubbles, with the whole room going at once. Her Neverland Mermaids are waiting on the other side, and they greet the birthday girl first, by name, before leading every child through into the party room.

The magic mermaid dress-up wardrobe, with tails and tops for every child

2Then

Together, they wish the wardrobe open.

Hidden in the forest is a wardrobe that only opens when the children wish it open. It does, and the tails are inside: rails of them, in every size, with tops and accessories to match. Every child chooses their own look for the day. Nobody is handed a costume.

Mermaid makeovers in the jellyfish salon for every guest

3Beneath the jellyfish

Three at a time, one mermaid each.

Three little ones at a time are taken into the salon and seated under the glowing jellyfish canopy, and this is the part that surprises parents most: every makeover is done by a character. Not an attendant in a uniform. Your child sits one to one with a real Neverland Mermaid who works on them and talks to them the entire time. Mermaid braids, colour and face gems, whichever she asks for.

Magical sand crafts, a keepsake from the mermaid adventureFully hosted character entertainment: games, dancing and nonstop fun

4Meanwhile

Nobody is ever waiting.

While the salon is running, another character has the rest of the room: magical crafts they take home as keepsakes, games, and enough going on that no child is ever sitting on the sidelines waiting for a turn. There is never a flat corner in the room.

The surprise mermaid tail transformation moment

5The reveal

The tail moment nobody forgets.

Then comes the reveal every mermaid party is built around. She is in her tail, on the clamshell throne, in front of the waterfall, and the room reacts the way rooms do when something genuinely magical happens.

The royal tiara crowning ceremony for the birthday girl

6The moment

She is crowned a princess of the sea.

Then the birthday girl is officially crowned in front of every one of their friends, with a crystal tiara they keep. The room goes quiet for it. This is the part that brings the whole party together, and it is the part parents tell us afterwards they were not ready for.

Mums, this is the one to have a tissue for.

Food and tea party service included for every childThe exclusive parents lounge with bar-top seating and complimentary craft lattes

7And finally

A tea party luncheon, served to them.

Everyone sits down for the celebration tea. Our staff serve the cheese pizza, the popcorn, the fruit snacks and our signature pink sparkling tea, so no adult is up and down from the table. You are in the parents lounge or at the table with a drink somebody else brought you.

You are not entertaining. You are not coordinating. You are watching.

Every Once Upon an Island party runs this way. What changes between packages is who hosts it and what she is transformed into.

You do not lift a finger

Your job is to watch the magic.

Most mothers tell us the same thing afterwards, and it is never about the decorations. It is that they got to watch. No setting up before, no refilling anything during, no staying behind to clean. You arrive, you relax in the parents lounge, and you watch your daughter find out she is a mermaid.

Professional entertainment

Behind every character is a professional team.

Our characters are on our staff. They host parties at our Newport Beach venue every week, their costumes and wigs are prepared by our own wardrobe and styling team, and they are trained to entertain rather than pose. That is what keeps a room of children engaged for two hours, and it is what lets you sit down.

Is food included?

Yes, and properly. Every party includes a catered tea party luncheon: cheese pizza, Pirate’s Booty popcorn, tropical fruit snacks and our signature pink sparkling tea, all served to the children by our staff. We love pizza because kids actually eat it. All of our food is catered, and if you would like to switch the menu, just ask. We do not include cake or dessert, but our team will cut and serve yours during the celebration.

The private venue, two to four Neverland Mermaids hosting from start to finish, a mermaid tail and top for every guest, the full salon experience, hosted games and storytelling, tea or lunch service, the crowning ceremony, the parents lounge, and all setup and cleanup.

1.5 to 2.5 hours depending on the tier you choose.
