Wave Runners on Seven Mile Beach in Grand Cayman

Does anyone on here know of where we can go, on 7 mile beach, where they rent wave runners at a reasonable price?  We will be cruising on the Destiny on March 27, stopping in Grand Cayman, and my DH wants to rent some.  We are a group of 14 so we need to rent several of them.  Needless to say, we want to find somewhere that rents them at a reasonable, somewhat economical price.  Any information will be greatly appreciated.  Thank you!

I'm not sure how much they rent for, but Royal Palms (the first piece of 7 mile you come to) has them.  We went there several years ago - beach chairs were $5 each, lockers were $4 each, they also rented snorkel equipment.  There's a bar and grill right next door for food and drinks while you're there.
