Hi there...yes i tried the river tubing in domenica and booked the excursion through Princess. Overall i liked it. I'm not super adverturesome, but it was just enough for me. You do go in a large group. I wish it were a little longer though but maybe its because I had a fun time that the time passed quickly. Afterward, they make you go to a little bar place. I personally thought this was pointless but overall I would def go again.
