We are potentially switching our 20th anniversary trip in mid-may from Puerto Vallarta to Grand Cayman. Right now we're looking at staying at tropical breeze B&B in breakers. Just a couple questions. I understand the beach just across the road from our B&B is on the rocky side. Does one just go to seven-mile beach or is it only for the hotels on seven-mile beach? Also, I assume we need a car for CI? thanks!
