We tried Shipwreck last year in August and much of it was closed, so call first to see if it's open and, if it is open, how much of it is open. We prefer big Kahunas but maybe that's because we didn't see enough of Shipwreck. Both are expensive entry fees which is why we like to go in August and go first thing in the morning because it's not crowded then and there are few, if any, lines.
