Just returned from the Glory, did the zipline & cave tubing with action boys belize.
The zipline was awesome, a big highlight of our cruise, wanted to do more, they were very professional and the equipment was very safe, we also really enjoyed the cave tubing, it was a little crowded though going thru the caves, but both a new and unique experience.
Donald and Tiny were very nice, and made everthing enjoyable, the only complaint I have, which wasn't exactly their fault, Carnival switched the day we were supposed to arrive in Belize from Tuesday to Wednesday, we found out upon boarding, we had booked a personalized tour for just the four of us. We ended up traveling on a bus with approx 20 other people , they said it was due to Carnival switching days into port, their guides were already booked for other tours. Due to the larger number there was not time to stop at the zoo or to stop for lunch.
We of course did not allow this to take away from this great family experience.
