Please Note

  • Birthday parties can accommodate up to sixteen children. Pricing is based on the number or staff required to host your party. A $50 charge will be added if attendance exceeds sixteen. 
  • Your party must be booked at least 2 weeks in advance to ensure availability of space and staff. 
  • Party programming is based on children’s ages and numbers in attendance to ensure age-appropriatness.
  • Please communicate any special needs or desires at the time of your reservation.
  • Payment must be received in full at the time of your reservation.
  • Because we frequently hold parties back-to-back, we ask that you respect other groups by waiting until your designated start time to enter the Club Room, and by leaving the room clean at the end of your 2.5 hour block. Our birthday hosts will have tables and chairs prepared for you, and are there to assist you in clean-up. 
  • Time slots are based on availability of space needed and thus may change seasonally as other YMCA programs are adjusted.
  • We will provide tables and chairs for your party. We do not provide decorations, food or refreshments but you are welcome to bring them. 

For pool parties

  • All children 12 and under are required to take a swim test upon entry to the pool area. 
  • All children under the age of 6, and children of any age who have not passed the swim test must be accompanied by an adult 18 years or older in the water at a ratio of one-to-one. 
  • Children who have not passed the swim test are encouraged to wear a Coast Guard-approved flotation device, which we can provide for your use during your visit. 
  • All swimmers must observe pool rules and follow directions from lifeguards as given.
