Always bring your own gear. Leave weights and tanks at home. Dive boats supply
weights and tanks. Rental gear leaves alot to be desired.
Cruise ship dive excursions cost more and are crowded.
Set you dives up by searching the internet.
Dive operators will acommodate your port arrival.
I try not to eat to much before diving. What goes in,
must come out. 1 is ok, 2 is a REAL prblem.
Here are some dive operators.
Grand Cayman -- Off The Wall Divers

Great dive operations. Very attentative. It is like
diving with your best friend. Can't say enough good things about them.
Cozumel - Aqua Safari Search the internet for their WEB site.
Nice operations. Better then others I have been on.
Personal preference though.
Good Luck and Dive SAFELYeyebrow
