And the tenders dock right in the shopping area. So its not like you have to walk a long distance to look around. IF you actually wanted to go into Belize city itself and look around, that is a bit of a walk and you probably don't have time for that. I would plan on starting your trip back to the ship about 45 mins before you need to be back. If you miss a tender you could have to wait 15 or 20 mins for the next one to leave... then another 15 20 mins for the drive to the ship.... So if you can manage to get off early then do so, you probably won't be able to because they will limit the first tenders for those with Carnival excursions and VIP (platinum members). so yes, Penny's 1 1/2 hours of shopping is doable...
