Much more relaxing than our typical cruise. We are usually taking lengthy and or strenuous excursions in every port of call, but on this itinerary there is not a lot to do besides snorkeling (excellent!), island tours, and the like. Not even much shopping near the port at some of the stops. All in all, a VERY relaxing vacation.
All the snorkeling we did was great fun, from the "drift snorkel: trip to the "swimming with rays and sharks" at Bora Bora. The highlight was a jetski excursion all the way around Bora Bora (not a ship-sponsored tour).
This is the smallest ship we have cruised on to date, and enjoyed the smaller size very much - didn't really miss anything except for a lack of many common areas to relax or use as meeting spots.
Cabin was fine. Larger than standard balcony room, but otherwise unexceptional.
