No guarantees on days and times of the boats.You can always rely on the island vendors and get what ever is in season.
Try Maria's fresh squeezed orange juice,try the new organic food service.Stop by the green house for fresh fish and lobster.Plan on using our local vendors,if your lucky you will catch a veggie boat it is "slow season".Fresh fish is normally by the lagoon side north corner you will smell them or see the birds,will be there a little past 7:30 a.m. I think.This is all Belize time,can easily change with weather and the Belize factor.
Enjoy your trip!
