Thanks everyone for your replies. It was exactly the info I wanted.
I knew that AC is an island (as is my home on Singer Island) and that the last leg would be by air or boat, but I did not know the jump off points of Corazol and Belize City.
On a tourist map, it looks like about a 250 mile drive on what looks like a decent highway. I had guessed about 5 hours and then a boat ride but it seems that my estimate was grossly optimistic.
