Don't have the phone number handy, but e-mail seems to be the way to go. When you check in, first thing they ask for is your e-mail receipt! Which includes the minimal deposit, so they can just charge credit card the balance. They are a short walk from the pier, just head left along the beach, go thru one set of traffic lights, Captin Bryan's is on the right side of the street shortly thereafter. 5 minutes, just watch the cars on the left! I booked thru grandcaymanexcursions.com, and had no problems.
