I don’t understand why this question keeps coming up, why are we always looking in yenem’s tup? Just because one chooses to stay home and make Pesach as usual it does not mean that another way is not as acceptable. Many of us run our own “Pesach Hotels” when our home is filled to the brink with family and friends. For us we are home, but for them what is the difference if they go to someone else or they go to a hotel? They are doing what is best and easiest for them and it is not OUR place to judge or comment.
People make various choices for a variety of reasons whether it is because the whole family cannot fit into one place, or the adults work and it makes it too hard to do a thorough Pesach cleaning plus prepare the meals, etc. Some people have physical and/or emotional reasons that prevent them from handling Pesach at home. Sometimes it is a gift from a very loving and grateful Husband who does not want to see his wife work so hard or parents who want to spend Yom Tov with as many of their children and grandchildren together. Many programs offer private sedorim rooms to accomodate a more heimish atmosphere. Usually the entire hotel is rented out for Pesach so you are among only Yiddin aside from the staff who are trained to accommodate you. They have children’s programs so both parents and child are equally entertained and cared for. The vast array of shiurim, minyanim, and other programs enhance the Yom Tov atmosphere in addition to the convenience of having everything under one roof and no need to go outside if the weather does not cooperate.
Pesach or any Yom Tov in a hotel is not for everyone, obviously. But as Yiddin we must understand that just because we do things one way, it does not give us license to criticize others who choose another path. It is perfectly and halachically permissible and therefore an non-issue.
