This is absolutely NOT true (or at least, not "always" true). 2 years ago we were staying at POP and our friends stayed in the room right beside ours. We had a knock on our door in the middle of the night and it was our friends letting us know they were being moved to another area of the resort because they had found their bed infested with bed-bugs and they had both been bitten.
We were never moved from the adjacent room (they said the resort was at capacity) and less than a full 24 hours later, there were new guests in the bed-bug room. We knocked on their door and told them about our friends finding the bugs and they went to look at the beds and sure enough, we saw the little buggers! They packed up everything and headed for the front desk to be moved. They were upgraded to Saratoga and before they left, came to thank us for alerting them.
Once again, in about 24 hours, the room beside us had guests. We went to talk to the front desk about the fact that this room was not being quarantined and they said they had sealed the room and turned the heat up for 12 hours to kill the bugs. Sorry, but that won't work.
We asked to be moved because we were terrified they would migrate to our room via the adjoining door but the manager said there was no evidence of a problem in our room therefore, they wouldn't move us.
We were lucky enough to escape the bed-bug problem, but Disney certainly didn't take it seriously.
On a side note. We also found 3 different live cockroaches in our room at the CBR a few years back and they were just as nonchalant as with the bed bugs. In fact, the CM's exact words were "so?"
I guess they felt that cockroaches were just part of the resort "theming".
While I realize Disney is far from the only hotel with these problems, their customer service when dealing with this (at least in our case) was appalling.
I'm so sorry this happened to you TNDISLVR, I really and truly feel for you and I pray your troubles will be over very soon and you will never again have to worry about these critters. Many blessings to you and your family and thanks for reminding us we can never be too careful.
One more note.... bed-bugs come from people carrying them into hotel rooms.
Please, please, please.... if you know you have an infestation of these critters in your home or elsewhere, and you are heading to a hotel while your place is being treated, make sure your clothes and luggage and "bodies" are free of these pests before bringing them into a hotel room and passing on the problem. You would only be perpetuating the problem which may come back to haunt you on another occassion.
