I was going to offer to pick him up and spend the day with us....unfortunately I arrive on the 16th so that is not going to work. If it were me, I would do go to Buddy and spend the day shore diving. The boat dives are nice but eat up a lot of valuable time and limit your UW time as opposed to shore diving where you can get in as much time as you can on a tank, exit, swap tanks and be back in the water in 15 minutes..... or better yet, do dive 2 or 3 dives at Buddy, grab a quick lunch and head up to Belmar (a buddy owned site) and do a dive or 2 there before heading back to the ship. Buddy does not open until 8 so you have time to get their easily......one thing you need to check into is the dive briefing. There is a mandatory dive briefing (not sure exactly what it is for cruise ship divers) so you need to figure that into your schedule.....
