Glad to know about your personal feeling about this.
Each has our own risk/reward criteria
That person was actually willing to take risk by going to theater and dinning indoors.
A lot of us cruise for many different points of enjoyment. For some an hour or two of indoor dinning was pain even before covid. Some felt same about those theater shows or bar scene or pools.
So why cruise?
Actually, all those things (theaters, casino, pool, bars, fine dinning) can also be done landside
Standing on top deck or front deck or back deck with great expanse of water in utter peace - can't get that landside.
Last Fall was amazingly wonderful time to enjoy traditional cruising.
Much smaller occupancy, both staff and pax behaving responsibly, no kids running around, no rowdy bar patrons and with tight sensible protocols risk of getting covid far less than a landside resort.
Guess that ship has now sailed....
