I don't know if most were eating in the buffet as we were always in specialty dining or the main dining room for dinner. Lunches, when we did the buffet, weren't very crowded but that was probably because people were on shore. I believe there were about 1200 on board. We were never told how many on board had covid, but when we returned to the ship from shore on a few occasions when going through deck 4 we did see the crew in almost hazmat suits and with medication trays going knocking on doors. We have no idea if it was passengers or crew who were ill. We had the drinks package so never had to purchase any alcohol or nonalcoholic drinks. There were signs on the bars stating only those with packages would be served while in ports. I wish I had taken a picture of the sign as I don't remember if it specified nonalcoholic drinks. I'm sure things like ice tea, water and juices were available to everyone. One couple we talked to were bummed because they were eating at Cagney's that night and couldn't get a glass of wine with dinner. It was a night we were in port till 9:30 pm. Hopefully, by the time you cruise, there will be more passengers and no masks. Either way, you'll have a great time!
