Looked for a short cruise while we were in Florida from Monday to Saturday. This one fit the bill. We have sailed Carnival before but not this ship and not a 4 day. But the timing and price were right so we took it. Glad we did. The weather was great each day. The ship was not perfect but it's not new and we didn't expect perfection. All the staff were pleasant and seemed to enjoy their jobs. Everyone greeted us with smiles. Compared to our last cruise on MSC, which was over-hyped and didn't deliver, this cruise was Very Good!
Only 2 ports of call were on this itinerary. We have never been to Key West but have been to Cozumel many times. I was surprised at the the arrival times for both ports - 7AM for KW and Noon for CZ. Many of the stores in KW were not open until 9 or 10 am. Since the ship departure time was 1 PM, that didn't leave a lot of time for shopping - which was okay with us because we packed light and could not take anything back with us anyway!!!
We simply wandered around KW with no plan except to take a photo and the Southermost Point in the USA. There was a long line of people there so we just got a photo of the monument and left. We past the Southernmost House, the Southernmost Southermost House, the Southernmost Hotel, the Southernmost Donut Shop, the SM this and SM that, etc...
Nice sized (average) cabin in good location. Near end of hall, short walk to stairs and elevator. No external noises. Slept very well.
Shops were not open until well after arrival. Did a lot of walking. Might try the fort next time.
Street vendors try very hard to get you to come into their stores but a polite "No Thanks" got us through all of them.
