Paradise on the Caye is awesome! It is the secluded Belize Beach you're looking for. A couple of tips: bring a lot of Off and something that can repel Doctor Flies if anything exists that can do it. Bring some groceries; we brought some Oreos, bread, peanut butter and jelly, and it was very nice to have just as snacks throughout the day. Do some research on golf cart rentals; ours that Joe and Leslie set us up with was a good deal. Just so you know what cost you're expecting, do some research and if you're not planning on leaving Secret Beach while you stay at Paradise, find out if there's a taxi to take you to and from San Pedro town (we did not research it). And most importantly, get ready to relax!
