Anybody do the Curacao Snorkel Cruise & Sightseeing thru Royal Caribbean?

Hi All

I was wondering if anybody has had any experience with the Curacao Snorkel Cruise & Sightseeing tour? It says Strenuous activity. I can't understand why when it is just snorkeling.

Also if this was worth paying for thru the cruise line? It is $74 now. I wasn't sure if there are outside agencies that do this excursions. I want to see the Sunken Tugboat. I have heard that is awesome to see.

Has anybody else seen the Sunken Tugboat?

Thanks

Dawn

Yep snorkling is ok but the beaches are crappy. Too much coral and is is yucky
