My best (funniest) breakdown was on the Norway ride. I am a "person-of-size" and so is most of the rest of my family. We were getting on the ride with another lady and her son. When we reached the boat, we let the castmember know that, in case she couldn't see, we were very big people and it...
You could also use those portable tiny fridges...I've seen them at discount stores for around $10.00 and they would prolly fit in your suitcase...worst case you could leave the thing in the room (to fit more souvenirs for the trip home)
