Sailing on the Carnival Miracle on 2/3 and booked this tour through cave-tubing.com. Just wondering if anyone else has done the Cave-tubing/ATV combo tour through cave-tubing.com? I'm just wondering how long all that takes and if you have plenty of time to get back to the ship. Also, they claim the video of the ATV'ing on their website was taken during the dry season. Can you give me any details on the ATV portion of the tour? Is it exciting or just slow and boring? If it's like it looks on the website, I'll probably cancel that portion of the tour and just do the cave-tubing. Thanks for the insight!
