while pedro's is an interesting stop that's on everyone's list, (including ours) i'm not sure i'd go there on my honeymoon. laugh

how about a sunset cruise?
day trip to a ruin
catamaran to caye cauker
snorkel hol chan/shark ray
walk up the beach at sunrise
rent a golf cart for a day and explore
arrange his/her massages
take a manatee tour
do nothing but stare at the reef
tons more...
