Itza and Huracan are a little more "rustic" and I would label Huracan as an eco lodge. We enjoyed our recent stay at Huracan and the diving was very good. Be aware that Huracan sits inland and there is no air conditioning, the fans they had were poor and the nights were pretty hot. You can read some recent reviews on Huracan here on this site and see some of my comments to those. I wouldn't hesitate to go back to Huracan, but a few minor improvements would go a long way in making things more comfortable. I personally would be a little concerned with Itza and it's dive operation right now. It appears they are in the process of establishing, or re-establishing, their dive program and I've seen some reviews about boat issues, equipment issues, etc. While we were on Huracan we dove with Elvis for part of the week who was the dive master from Itza. He was great, but of course we used Huracan's boats and boat Capt. I would ask a lot of questions about boats and dive staff/equipment before I'd consider booking there. Of the two I would go with Huracan. Another option, depending on what you are interested in, would be Turneffe Island Resort. You primarily dive Turneffe but on the Blue hole day you get two other dives, one off of half Moon and the other off of Long Caye, in site of Huracan Lodge. TIR runs a great operation, and I have nothing but good things to say about them. We've stayed three weeks there in the last four years. They often run a special, which I think is still currently on, that is a pretty good discount for bookings until the middle of December.
