To those criticising the William and Kate's itinerary, you do know that they won't have devised it themselves; they weren't going on holiday and able to chose what they wanted to visit or do. Scuba diving in Belize could very well have been chosen by the Belize government as an opportunity to showcase the country's visitor attractions (tourism being a major part of their economy). A royal visit is a good publicity vehicle.
And until we know just who was responsible for the open top Landrover idea, the UK govt or the Jamaican govt, it's really not possible to say whether it was a diplomatic boo boo or just a reference back to William's grandparents' visit.
Planning a royal tour, this from 2019:
Royal tours can take up to a year to plan, and are either instigated by the U.K. government, or by an invitation from the host country. The itinerary is put together based on whatever matters of national importance the host government would like to draw attention to, while also incorporating some of the visiting royal's personal interests.

I haven't followed this tour particularly, not being very interested, but it seems to me that the scuba diving has really upset many people on here. I fail to understand why.
