The Greatest Threat to Judaism?

The complete letter by R. Yaakov Horowitz about whether hotels on Pesach are the biggest threat to Judaism (discussed in this post) is now on his website: link

UPDATE: I should add that I've never been to a hotel for Pesach, have no desire to go to one, and can't imagine what the experience is like. While it is expensive, people often pay that much money for a good vacation. As a working man who saves all of his vacation days for Yom Tov and Chol Ha-Mo'ed, and doesn't get holidays, summers or mid-winter vacation off like many educators and rabbis, I can understand why people might want to spend the only vacations they have during the year (Pesach and Sukkos) away from home. I have always gone to family for some if not most of Yom Tov.
