Are you staying at Aquamarina Suites and your wife at the Blue Tang, or vice versa?
I highly recommend the Blue Hole dive day with Amigos del Mar. Do a search on the Blue Hole and you'll see some great posts.
A couple of the bars stay open late, late, late. I've never stayed long enough at Daddy's to be told it was closing time and I've been there late, late, late from time to time. (never the night before the Blue Hole day though, of course. Um, well, OK there was that one time, but on my way home that morning, I told them I wouldn't be going and I had to pay for it anyway. Served me right.)
