Sorry Nutmeg but I have to agree with TravelHat - stay on the boat.

The best thing about Belize City was seeing it fade in the distance as our ship sailed away. We've cruised all over the world and Belize City was, without a doubt, the worst port of call we've ever made. the area around the tender dock was just as bad as TravelHat described. We took a land tour up New River to the Mayan ruins of Lamanai which took as twice as long to get there then it did for us to explore the "just OK" ruins. The whole day was a waste of time and money.

Stay on board the ship.
