While the theme park moniker is pushing it (the kid-orientated facilities consist of some blow-up water slides and a rusty go-cart circuit), this place on Walter Fletcher Beach offers a decent spot to relax in a nonthreatening local environment; the cruise-ship day-trippers usually get bussed off to plusher Doctor's Cave up the road.
The beach is sandy and relatively clean and the water is safe for swimming with some limited snorkeling possibilities. Food and drink comes courtesy of the onsite deck-bar with things heating up at sunset especially at weekends. Look out for billboards advertising sporadic live-music events.
