Mildly OK. Tendering sucks and takes WAY TOO LONG. Get to the Encore Lounge early and be prepared to wait, wait, and wait. Get off of the tender and wait, wait, wait some more. The cave tubing excursion is breath-taking once you get in the water and start tubing. Just beautiful. The hike to the river isn't bad, just 20-30 min long. The ride from the port to the tubing center is 1.5 hours long. DON'T BELIEVE THE TOUR BOOK - IT IS 1.5 HOURS LONG. Whether they tell you or not, you get a tour of Belize City and the country side on your way to the tubing center. I could have done without. I would have rather had more time on the river. No quick rapids/currents on our tour, but this does change. There have been fatalities on the river and in the caves. I wouldn't take kids on this one...make this adults only with swimming experience. I'll never go back to Belize. It is too poor and just unappealing. The water and temperature is great, but there isn't anything I'd like to do there other than stay at a well protected all-inclusive resort. I don't dive or snorkel, so that might be worth a trip back for some people.
