Does anyone know why so many of the Bermuda shore excursions have a weight and height limit on them? I would expect that for certain excursions that dive or something like that. But in the Royal Caribbean shore excursions for Bermuda, there are weight and height restrictions for virtually every excusion, like simple bus sightseeing, trips to the beach, boat tours around the islands and stuff like that. I don't really understand why simple excursions that just transfer you to the beach for the day, or drive you around a town to sight see has these restrictions?
