The drawback to this plan is that some hotel employees may not be able to get to work, and some deliveries may not get delivered. So plan to eat all the canned food the hotel has on hand, and reuse towels for as long as it takes. I learned this in New Orleans for 5 days stuck in the Westin hotel with 2 children under the age of 2, during Hurricane Georges
I packed fresh cooked meals and shelf-stable foods. My cousin already made guacamole with my avocados. Oh, and I baked cookies this morning. No worries.
