We have been there and snorkeled four times. The sunken Mickey and Minnie are a ways out...farther than it looks. I am thankful for the required inflatable life vest because the farther out you go, the deeper it gets...it also is less cloudy. There are life guards stationed a ways out there, but I found I needed the vest (inflated) to take a break between sunken treasures. Look for the floating buoys that mark the sunken items. If it looks too far for you to swim, don't do it...it is almost to the rock reef. As far as fish, it is totally random. We bring our own equipment, except for the vests (which are free and located at the lifeguard stations). Be sure to take a camera. As I said, things are somewhat random, so you don't know what you might see or when. Great fun, roped off and free. Keep swimming, swimming!!
