When I was a kid in Disney, in 1978, we had a room that was overrun with palmetto bugs at the Poly. My parents called to ask for the room to be exterminated, but we got moved, so did my aunt and her family since we had adjoining rooms. Bugs are a part of life too, especially in FL. Mgmt took care of the problem quickly and well.
I agree, lice and crabs are brown and almost microscopic. White crawling bugs sound like termites, which wouldn't have hurt them but still aren't fun to look at, much less share a bed with. And I wouldn't have waited until the morning. I would have been at the front desk, ASAP, in my birthday suit if necessary, complaining loudly and frequently about all the bugs in my room- that would get some action fast!
