Tiama Catamaran lunch cruise vs. Glory Tours

[mom-to-2]

My husband & I are on the 3/21/04 sailing of the Norwegian Sky going to the S.Caribbean. During our stop in Barbados we are deciding between the Tiami Lunch Cruise for some snorkeling and the Best of Barbados through Glory Tours. I've read great reviews about Tiami. The price is right with Glory and in addition to snorkeling we see several sites on land. Has any one "been there, done that" and can give us their opinion. We are having a hard time deciding and our departure date is quickly approaching!
