Did the Atlantis sub tour in Barbados on April 5th. Was 99 if you booked thru Princess, was 82.50 online which I booked.
I was a 'neat' thing to go down 142 feet, however, I wouldn't pay for it again. You see a few fish, some coral and at least on my tour, a sunken ship.
Check the photo gallery in a few days... by Wednesday night I should have my review of the Sun Princess March 30th trip and will post extensive pictures of all 6 stops including for you a few pictures of the sub and what it looks like out the window of the sub at 110 feet down.
Like I said, it was a cool thing, but I believe my time and cash would have been better spent doing something else.
the photo gallery name will be Lex's Sun Princess Trip
cheers,
Lex
