If you are planning to spend anytime at the pleasure island clubs, then it would be worth it to attend to get the free admission wristband for the clubs. There were arcade games for the kids and face painting and coupons for ice cream, crackerjacks and popcorn. If you have no children, then you should get there later, at around 6:30PM to at least enter your name in the raffle for the gift baskets.
Our group had a great time at the comedy club and the adventurers club. Something we probably would not have done on our own, had we not received the free club admission.
