Hi: Ok...got our cruise package and now I see what is available for excursions. I'm not into scuba but would like to snorkel. My question is that is it really nescessary to go with the excusion in order to do some decent snorkeling. Also, if I want to go sea Kyaking, can I rent one on shore without going through Princess? Going on Dawn 11-18 out of PR
, Thanks again.
