I admit it -- I don't pay attention to kashrut any other time of the year, but I do make it a point to do so during Passover. (There is a very logical reason for this but I don't want to go into it as it would get this thread into a theological debate.)

I find it very difficult to manage this while travelling. Yes, airlines will provide me with food which is kosher for Passover and if I am going to a city with a decent-sized Jewish population I can find supermarkets with at least basic foods which I can eat in my hotel room.

Beyond that, it is difficult. Most kosher restaurants close for the holidays as they don't want the expense of maintaining the extra sets of plates, utensils, etc.

This is true even in Israel -- and much more so overseas.

How do you handle this problem?
