We’re a cast of characters! Surprise your child with a special character visit during his/her party. Characters will drop in during your party for up to 20 minutes for pictures, interactions & more!

Character visits are part of what makes Cowabunga’s one of the top New Hampshire birthday party venues – they are the ultimate party add-on! Visits are recommended for private parties, as this allows dedicated time without distractions from other kids. Character visits can be done during your private play time or in the private cake room. Your party planner will talk through the options with you.

Princess & Superhero visits are extra special, but only done on a very limited basis at Cowabunga’s in Manchester. While we work really hard to staff these visits when requested, we have very limited staff options that fit the “look” of each character. Sometimes princesses will wear wigs, and characters may be required to wear masks during their character . Please inquire with the store manager about your special character visit.

We will contact you the Tuesday before your party to go over all the details of your party.  During this time, you can order food, balloons, goody cups and add a character visit.  All orders must be in by Thursday at 3 pm before your weekend party.

We ask that you bring your party supplies with you on the day of your party!  

Public parties will be able to decorate the party pavilion at the the start time of your rental.   

For private parties, we will have plenty of time to decorate while your guests bounce and play!  Typically, your party pros will start decorating 40 minutes after the start of your private party. Since our private parties follow the same rotation, you may not have access to the cake room before then, as another party may be in there.

Typically we can not accommodate requests to come early, as we have other parties using the space before your party.

We work our magic & everything gets cleaned and sanitized between parties but doesn’t allow for time to set up early.
