We just came back from a Disney Cruise in the Mediterranean (Spain, France, Italy, Croatia, Malta) July 25 to August 6. The trip itself was awesome (food, entertainment, service, excursions, etc.) but we had the nasty visit of bed bugs. I got more than 100 bites; my wife nearly a hundred. The frist day I got bites I thought it could have been mosquitos while onshore, so did not report it, but the second day I was covered by dozens of bites. When reported the crew did find bed bugs. They did on the same day change us to a better room and offered medical treatment (and they washed all of our clothes too at high temperature, just in case). However, their only compensation was 150 US$ per person. After we moved to the new room no one ever asked us how we were doing.
The room next to ours had also bed bugs. The people there were also moved.
