We chose this cruise back in October, before omicron, because the price was a steal. When it cam close to the cruise date, we were beatinng whether or not to go (and lose $2000 if we canceled). but we were upgraded a week before to a penyhouse "suite", so it was hard to pass up. We had to test negative for COVID within 48 hours of our flight to San Juan and, again, at the dock bfroe boarding. We had to wear masks in public areas. Social distancing was easy (the cruise was designed to be at 50% capacity and it turned out it was only at about 33% capacity).
The Caribbean cruise was lovely. St Thomas denied us docking, but St Kitts, Dominica and Tortola went smoothly (except that one could not get off the ship in Dominica unless you were on an official tour). Despite that, we had a great time. The level of service and the qulity of food was extraordinary. I suppose it would have been more fun without the masks, but it was great to have so much space and privacy and attention from the crew.
Because the Crystal owners were having financial woes and owed several millions for fuel, a judge in Miami put the ship under "arrest" a few days before we were to terminate in Miami, so we diverted to Bimini in the Bahamas rather than ending up in Miami. Because of this, we all missed our connections but we (at any rate) easily rescheduled our flights. We did get an extra day of the same level of service and amenities on the ship for "free." The only really bad part was the ferry that took us back to the US from Bimini to Fort Lauderdale. It was crowded, a fair number of people did not wear their masks and the seas were very rough. Some people were miserably seasick for what seemed like an interminable 2 hour trip.
Very nice cabin, about the size and level of "luxury" of a Seabourn veranda suite, with the addition of Butler service (which we didn't use much). Also, the PH guests can eat in a specialty restaurant every night if they wish with no added fee.
