1) According to many, many rabbonim, (I know personally my rav screams against it every year)it is so difficult to not be oiver any issur chometz in a hotel with goyim staff/workers. I’ve heard from mashgeechim too, it is possible, but many areas where there can be problems you would like to avoid. Look into it.
2) It is so important for children to see parents pesach cleaning and getting involve in preperations for Yom Tov. One kid I know thought goyim were supposed to build sukkos FOR us because a goy builds it FOR them EVERY year! Imagine a kid doesn’t know what it means to clean the house from all chometz because throughout his childhood he never saw his parents clean and get involved in cleaning or Biyur chometz, -instead it’s close up shop, and fly to a hotel for Yom Tov. Where’s the spirit? where’s the joy of ‘shvitzing’ for a mitzvah? baking your own matza? It’s all part of the beautiful Yom Tov. Going to a hotel is cheating yourself from all the ‘fun’! Save your vacation for a different time of the year. Just my 2 cents.
