Booking Terms

Deposits are rounded to the nearest five pounds at checkout. Payment upon booking confirms the availability request of your chosen services and secures them against the date and times you’ve requested to be confirmed. We require a non-refundable 35% deposit to book any inflatable online. A secure payment link will be generated after completion of the booking form. Please ensure payment is made before the session times out.

The remaining 65% must be paid before 3pm, 1 day prior to your delivery date. Within your confirmation email will be a secure payment link to pay the remainder of the balance online.

Amendments & Cancellations

All bookings are eligible for free amendment / cancellations within the first 24-hours of booking. Amendments made after this time are subject to a £5.00 administrative fee. Please see terms of business documentation for full clarification.

Overnight Hire for Inflatables

You can opt to have overnight hire (available at an additional £30) with collection the following day before 12pm, if you have a lockable garden gate and a surrounding fence of at least 6ft height. As at all times through-out your hire, you are completely liable for the safety of our equipment.

You do not need to opt for overnight hire if you choose to have multi-day hire. The price already includes this.

By making a booking with us, either online or via phone, you understand and agree to these terms.

3D Mermaid Themed Bouncy Castle Hire 🧜‍♀️🌊

Make a splash at your next party with our magical Mermaid Themed Bouncy Castle – a bright, under-the-sea inflatable packed with colour, character and extra fun features that kids absolutely love.

Underwater Adventure for Little Mermaids 🐚

Perfect for birthday parties, family celebrations, school events and garden parties, this curved bouncy castle surrounds children with friendly mermaids, sea creatures and ocean graphics. The arched design helps keep the play area feeling cosy while still giving grown-ups a clear view for easy supervision.

Pop-Up Sea Creatures for Extra Fun 🐠

What makes this castle really special are the built-in activity pop-ups on the bed of the inflatable. Children can:

  • Ride on the seahorse and sea-creature pop-ups as they bounce and play
  • Dodge, weave and bounce around the soft obstacles, turning the castle into a mini adventure zone
  • Enjoy the eye-catching 3D shell feature at the top, which gives the castle a true “under the sea” look in your party photos

These interactive features keep children entertained for longer and add an exciting twist compared to a standard flat-bed castle.

Safe, Clean & Reliable – Every Time ✔️

As with all Zunzo Party Hire inflatables, our mermaid castle is cleaned, safety-checked and fully insured before every hire. It’s built from high-quality, commercial-grade materials and is designed with younger children in mind, giving you peace of mind while they bounce and explore.
