I tired to fine the link but wasn't able to. Sorry. On our last cruise some friends of ours did that and it was expenses but they enjoyed it. They only take a few on that tour so booking early is good.
Haven't seen it in years but on RCC lines they had it on your TV so you could watch it. Pretty impressive.
