As mentioned, shore diving is the norm. With a rebreather you can hit several of the reef sites in one dive. There are no SCUBA police, so you can make your dive group as small as you like.
Walt set me up with tanks and lime. Dropped the gear off right at the resort. Just contact him in advance to let him know when you arrive, and what you'll need.
