Before Covid, my wife and I and our band frequented "less pricey" cruises in the waters of the left coast... Most of these trips were bluegrass cruise events, sort of mini-festivals with 50 to 100 bluegrass folks from somewhat random parts of the continent. Our band was frequently part of the "entertainment" for these bluegrass events, but not as cruise employees. That said, we got to know a number of the cruise employee musicians, often at first because they'd notice our instruments -- it's hard not to notice a double bass being loaded onto a cruise ship -- but also because we shared a love of music
For these "less pricey" cruises, the ship musicians we met were generally a friendly lot, but like most of the cruise employees they always seemed tired, running a tight schedule and working multiple different musical genre areas of the ship, frequently supplying entertainment nearly around the clock for various venues for weeks and sometimes months at a time. They often reminded me of summer camp staff -- over worked, under fed, under slept, under paid and often just plain overused. Often they managed the sound equipment they were going to use for themselves, although some of the ship's larger venues had their own assigned sound people.
We occasionally joined a few cruise musicians for their sets, and occasionally they would join us for some of our sets or jams. They could tell we were serious at our music and loved it,while we could tell they were tired of their music and routine. Often they would join us during their breaks for larger spontaneous jams that would form on various decks on the ship and we could tell they were enjoying the musical freedom we shared.
As musically oriented passengers, our impression of the cruise-provided music was that it was almost always way too loud and crowded, and perhaps somewhat rag-tag. Mostly pop covers played and/or sung for passenger audiences that were pretty often over-supplied with alcohol and almost always over-supplied with food... Often the stereotypical cruisers; grandma and grandpa, but also sometimes the younger family getting away, and also sometimes the Leisure-Suite-Larry lounge lizard crowd. Since we often shared venues during off-hours with the ship's bar musical staff for scheduled jams and other event programming, we'd sometimes use ship sound equipment and sound people, so we'd get to know them too.
We always left the ship feeling like we were the lucky musicians; the music we performed was at sensitive volumes, largely spontaneous, songs done by our choice under little or no schedule pressure and it was generally the music we loved -- in stark contrast with the cruise provided music. While we could imagine ourselves as cruise-employee musicians, we really couldn't imagine enjoying it for long, and most of the time we felt sorry for the cruise musicians we met.
Covid has had a marked effect on all of the cruise ship lines as well as bluegrass events on them. For employees on cruises it has meant an increasing work load for fewer passengers with dramatically higher risk of getting sick for both employees and passengers. As older folks, my wife and I personally have not attended a cruise since late summer 2019, and we still don't feel comfortable about doing so; even before Covid I frequently caught the ship's endemic infection on each cruse by the 2nd or third day and had to spend at least a day in bed, so chances of me catching something worse now are high. We have concerns for all the staff, including the cruise musician friends we met.
