I never understood how people went to a hotel for Pesach. (I definitely dreamed of not having to clean & cook, but a hotel seemed strange to me). A few years ago we were going through a very stressful time. And I was also exhausted as I was at the beginning of my first pregnancy (we had been married for many years, already). We went to speak to a Gadol about 3 weeks before Yom Tov (about the situation that was causing the stress), as we were finishing our conversation we mentioned that I was having a hard time preparing for Pesach because I was so tired (we had been unable to find a cleaning lady). The Rav told us we should go away and given all the circumstances a hotel was the right place to go. We went to a hotel run by someone we were familiar with and it was an amazing experience. We were able to relax and enjoy yom tov without added pressure. While it is not something I would do on a regular basis I will always be grateful that that option was available to us when we were told to avail ourselves of it.
That having been said, there are a wide range of hotels available. From whet I understand, some seem to focus more on the Yom Tov and some more on the ‘vacation’ aspect. Obviously each person must do what’s best for them (after consultation with their Rav), but I think that the focus of the particular hotel must be taken into account.
