I choose this cruise as it was going out of St. Maarten and it not only required guests to be vaccinated but also had to submit a covid test 3 days prior to the St. Maarten Health Department. That was great but intimidating as we were so dependent on getting our PCR test back within 24 hours (or it could have been an antigen test). If a PCR it could be taken 3 days before departure, not a minute before by the way, or 48 hours prior if antigen, so timeframe for them to receive it and confirm the same. We got our results in 24 hours but then dependent of the Health department to accept it. An extensive health form had to be sent to them. It all worked out but hated being dependent on the internet and outside sources at the last minute.
We had booked a similar itinerary out of Ft. Lauderdale on Celebrity but as Covid increased there we just did not want to risk it. Unfortunately our payment in full could not be transferred over to St. Maarten cruise so had to pay again. A bummer, but we now have a credit towards our original cruise to Canada that was cancelled.
Anyway, cruise was great. Only 385 passengers on it. It can accommodate 2,200. So only 20% full. It was very strange to be on a ship with such few people. Really missed the opportunity to socialize with more people as we were rarely near one another at meals which is when we usually have a chance to socialize.
