omg why do I torture myself reading these threads?
Zip covers for mattresses and pillows/linens from home are sure sounding good about now
The idea of lice scares me worse than bedbugs! BLECH!!!
I checked for them on our last several trips (some to disney some not) and have not seen evidence. We stayed at Poly for 9 days last fall and we all got sick (some bug was going through the resort population everyone sounded like they were hacking their lungs out

but no bugs.
If I saw a speck of ANYTHING on ANY bit of the bedding, I'd be out of that room so fast it would make heads spin !
I disagree too with the whole 'foreign' travellers thing. People always want to blame someone else for their troubles. I think we have plenty of bugs right here in the US we don't need to try to point a finger at any of our international visitors to explain it.
Going to the super-mart on any given weekend in our particular neighborhood is all the confirmation you need that some people who have lived here all their lives seem to have an in born aversion to soap and deodorant
