Q What do you have to do (when attending a Pesach hotel) with the food and liquor on the room fridge?

A. Minchas Shlomo (2 p. 237) rules that since the hotel guest is generally responsible for the contents of the fridge as he has to pay for them if they are used or go missing, he would transgress on the chometz prohibition. Therefore he should request the hotel administration to empty out the fridge contents as soon as he arrives.
Horav Shlomo Miller’s Shlit”a opinion is to be stringent since the guest could be held responsible. He also suggests that if the administrators refuse to empty the fridge or will not be able to do so on time before the prohibition of chometz begins on Erev Pesach, he should ask them to lock or seal the fridge, and he should declare that he does not accept any responsibility for the contents.
