I had yeshiva friends who worked as pesach hotel mashgichim. Many of them had horror stories, and wouldn’t trust hotel kashrus.
Some letter writer to the Yated once pointed out that in the zman beis hamikdash, it was considered perfectly acceptable to leave your house and go away for Pesach. True enough, but I wouldn’t compare the ruchnius of a “glatt kosher decadent luxury hotel ” to “sleep in a tent on the road with your animals with you” experience.
