I think what everyone's trying to get across is that you're no more likely to come across bedbugs at Disney World than you are anywhere else, therefore there's not much point in worrying about your upcoming vacation.
Also, it's important to remember that just because something is mentioned in the media frequently doesn't mean it happens frequently. Bedbugs are icky and scary and attention-getting, and that's why they're all over the media. To get to you tune into that night's newscast, or buy the newspaper or magazine, or go to the web site. There's an old saying in the news biz...."if it bleeds, it leads." In other words, if it's sensational, put it right up front, and people will tune in.
Yes, I'm aware that bedbugs are more prevalent than they used to be. I do a quick check of the bedding and mattress before I settle into a hotel room. And then I don't give it a second thought for the rest of my vacation.
I don't want bedbugs in my home, that's for sure. But the only way to be 100% sure I won't get them is to stop going to stores, movie theaters,theme parks, and stop taking flights and staying in hotels. But that's not an alternative I'm going to choose. So, I accept the risk,and if it happens, i'll deal with the bedbugs.
Long, roundabout way of saying that I'm not going to spend any time worrying about bedbugs.
