The Yellow Sub certainly has the benefit of walking distance from the pier. If you have a way to get around (and I assume that is an option if you are talking about Habitat, Buddy Dive, etc.), you might try the Cliff from Dive Friends @ Hamlet Oasis. While there isn't a dock, the facility is setup for an easy entry and it's a very nice dive with easy navigation. The tanks are handy with helpful staff and a good setup area in the shop. The shop also has good rinse & outdoor shower facilities. There are wide steps down to the entry and a big rock at the entry point you can use for hand holds (balance) as you enter. There is also an underwater cable that leads out over the drop for easy navigation (Habitat & Buddy Dive both have navigation devices as well) and again the Cliff is a very nice dive. Just another option. Have fun.
