Sorry, I created some confusion by using the term "weekend"loosely. The trip itinerary goes something like: (a) fly into Grand Cayman Thursday night; (b) 2 dives Friday; (c) 2 dives Saturday morning and a night dive Saturday night, (d) if you want to go for AOW, you can do additional dives on Sunday morning, (e) leave Monday, 24 hrs after your last dive on Sunday.
