OK, we have a tight schedule on Grand Cayman. We are on the morning Stingray City snorkel that reurns at 11:15, and then have an Atlantic semi-sub we booked on our own at 1. Can't find a really detailed map of GeorgeTown online - how ar from where the excursion drops us off to the Atlantis dock (by Hard Rock)? Anyone eaten at the Hard Rock there? How was the service?
