We had a prior trip with Silver Seas in the Mediterranean (last year) and had a fabulous time. We really enjoy the size of the silver seas ships (small ships with some big ship amenities) - less the lines for everything. While this Caribbean cruise was not quite as well pampered as the Mediterranean one we took, the experience was excellent. At the outset of the cruise, it felt like an inordinate number of staff were working for their first time - the service did not feel as personal or attentive and we regularly met with lines (which we hate). This got better as the cruise went along.
The ports of call were spectacular, a nice combination of ports with other big ships (and amenities to go with it) and small quiet coves that are more "island" in nature. We enjoyed that. The included excursions were also excellent with a nice combination of relaxed and adventure options. We took advantage of a rum distillery tour, two zip line tours, two snorkeling tours and a helicopter tour of the Monserat volcano (which was excellent, but not included).
All in all, we would recommend this cruise highly and would love to do it again.
We had three in our cabin (including our 6 ft plus 14 year old son) and were reasonably comfortable. The veranda was nice. On a prior tour, we stayed in the silver suite, so we are a bit spoiled as that was a double bay, huge suite.
