See FAQs below for details.


  • Who can go on my membership?
    Family Memberships are good for 2 named adults and up to 6 children (under the age of 18) from the same household (same primary address). Family memberships can be purchased for yourself, or as a gift. Memberships are good for one full year from the date of purchase. Individual Memberships are good for 1 named adult, and 1 unnamed child or adult guest of their choice (“adult” or “child” must be selected at time of purchase and cannot be changed until the renewal period). Guests must be accompanied by the primary member.
  • How can I add extra guests, caregivers, or grandparents to my membership?
    To cover anyone outside of the member household, we have introduced the Extra Guest pass. The Extra Guest pass is an unnamed guest on the membership that may accompany any listed member throughout the year. Extra guests do not have their own membership cards, as they are not listed members. Up to 2 extra, unnamed, adult guests (babysitter, grandparent, family friend...) may be added to a membership for an additional $10/adult/year. Up to 2 extra, unnamed, child guests (cousins, classmates, random neighbor kids...) may be added for an additional $5/child/year. Extra Guests can only be added to Family Memberships, not Individual Memberships.
