Been to SCC twice and loved it. The only drawback is they have probably the slowest boats on the island, so the trip can be over an hour each way. I remember eating lunch well after 2 PM some or most days. Still, the employees there are very accomodating, and we met some great people (other customers) that we dove with all week, and then booked a second time with them a few months later.
Next time we may try another place just to not go the AI route, but plan to return to SCC at some point. The included tanks for diving off the pier, especially at night, are nice, too.
That's one of the many things I love about SCC. I always run into people there that I've met before. They have a lot of repeat customers and they are mostly divers and a friendly group. I like the other hotels too, but really like the atmosphere at SCC when we all get back from the dive and exchange stories. Not a lot of kids there either. Just divers! Grand Occidental is nice and close to the sound end too, but really lacks the dive comradery (sp?) we had at SCC.
