This is proving to be tough to accommodate such a late arrival time (10 AM) and early departure time (6 PM).
This is what the various ops state on their website regarding cruise ship passenger dives:
Dive with Martin:
Blue XT Sea Diving:
Dive Paradise boats leave at 8:30 AM.
Aqua Safari boats leave at 8 AM or 8:30 AM.
All of the afternoon boats will return too late for the ship.
Dive Palancar is the most promising, with a boat leaving every 2 hours from 9 AM for 1 and 1/2 hours. So if I can get on the 11 AM boat and do 2 dives, or next choice a dive at 11 AM and then 1 PM, that will be perfect. I sent an email to them, hopefully it will work out.
Thanks for all your help!
