I don't agree with amy... we went on the river tubing at Chukka Cove, and thought it was great!!'There was nothing boring about it!!
Admittedly, there were no huge rapids, just a few small falls, but it was a lovely trip through the jungle, with a very funny group of guides, who were joking and singing songs all the way!!
If you want "danger and excitement" , maybe it's not the trip for you... but it's sure safer than cave tubing in Belize!!
Also... about feeling bad about the poverty... every time a cruise ship pulls into Jamaica, it brings extra revenue to the country.... tourism only helps the economy.
