We have always taken an electric cooler with. It has never been a problem to have it in the room. In fact this yr at ASMu they delievered it to our room and plugged it in while we were in the parks. HRH also kept it plugged up all day in storage until we came back in the evening and had our luggage sent up.
They are also lighter weight than the small refrigerators so it should cost less to ship back home. Walmart, K mart and Target carry them as does most stores that carry camping equipemnt.
