I'm also in the same position. Nothing set on stone and my trip is coming this weekend. Doing a trip with my partner. We are both young and energetic. Our big problem is that We only have two days in Belize.

If you had only two days in Belize (more like a day and half), where would you go?

I'm thinking on going for a day trip to some Mayan ruins and cavings. The cayes look like a fun place to go but going on a plane or water taxi doesn't seem the best use of time/money.

Is there anything interesting to see in Belize city?
