You and me both!
I am not so sure about the close quarters and I like my creature comforts, so we'll see how this goes. I have been on 2 liveaboards in the past, one was off Catalina Island set up similarly to Blackbeards except only our LDS was on it at half capacity, so we each had extra space and an extra bunk for luggage. Last year I was on a very nice liveaboard in Jardines de la Reina, Cuba with private cabins, private washrooms, top notch service, and lots of space. They were very different experiences but I had an awesome time on both and had fantastic dives.
I also wonder how the diving will be, especially after the hurricane. I am going in with an open mind, however, and I'm sure I'll enjoy whatever I find. From when I last checked, there seemed to be some minor damage around Paradise Island, a bit around Nassau, but I didn't hear anything about the out islands like the Exumas, Eleuthera and San Sal. So hopefully the reef and life weren't too affected.
I'll try and post about my trip after I return from my few extra days away after the liveaboard and catching up with photos and life after.
