I actually think more people would spend Succos at hotels too if it weren’t for one teeny little detail: you have to eat in a sukkah on Sukkos.
The Hotels could easily build a succah, many already have outdoor gazeebos and could turn them into succahs.
In fact in Brooklyn or Manhattan for many eating in a succah is actually not so easy as they live in Apartments and there arent open spaces to put them
(Some put them on balconies or Roofs if they are allowed) and in Williamsburg Ive seen them on the Sidewalk, but for many a Succah is not really possible
