In the winter, I look at balconies as refrigerators. For example, you buy cheese, you store it in a plastic bag or tupperware container on your balcony. Forget smelling up the minibar in your hotel room.
In fact, we were at the Park Hyatt last month and the minibar is a joke. No good place to store your own stuff, just overpriced hediard nougat. Anyhoo, we were not allowed to store our own cheese in the cooler at the hotel (fine), but we couldn't get ice to keep things cold over night. We ended us throwing out some cheese.
So, if you are a cheese lover, want to store some clementines, yoghurt, milk, cold water for your trip, then look for a balcony.
