We decided on the Tahitian Princess. Will take our own snorkel gear. I know the PG is wonderful, but we will try out Princess for the first time. This is our 10th cruise, and 2 have been on Crystal. We made up our mind to give the Tahitian Princess a try on our last Crystal cruise, which was through the Panama Canal. One of our tablemates had taken the TP a few years ago, and said she found minimal differences between Crystal and Princess. So we will see for ourselves.
