A friend and I decided on this cruise for two main reasons: it had very unique ports-of-call -- St. Croix, St. Kitts, Dominica, Grenada and Tobago -- and it was on Celebrity. We had both previously sailed Celebrity Solstice, which we thoroughly enjoyed. But we knew Summit was a (relatively) older ship that didn't have all of the Solstice-style features -- so we may have gone in with lower expectations. However, we found the ship to be very well-maintained and laid out, and the smaller size only exemplified Celebrity's tradition of excellent customer service.
With so many cruises calling upon the now-mega ports of St. Thomas and St. Maarten, it was a refreshing change to have an itinerary which focused on the smaller and far-flung islands in the Caribbean. This was not your shopper's cruise -- there were no massive malls with countless jewelry shops (except maybe in St. Kitts) and tacky souvenir stands were kept to a minimum. Instead, you could find unique outdoor markets in the towns, gorgeous beaches and stunning scenery elsewhere, and genuinely nice people. For example, I found my taxi drivers to be more than happy to talk about their island homes and the cultures and traditions.
Back on board, the service was top-notch. From the stateroom attendants, to the dining staff, to the events coordinator Rose (who arranged several Cruise Critic events for us), to the officers and the Master himself, we were always greeted with smiles and kind words. Oh, and often drinks -- at boarding, each special event, reception and even reboarding the ship after our last port-of-call, the staff were greeting us with glasses of wine and champagne. With the bigger cruise lines finding new ways to nickel-and-dime their passengers, it was nice to see Celebrity extend their appreciation of their customers in this way.
Nice cabin, not too small. Could have used some more cabinets/storage, which newer ships have done a better job with.
