I don't think they're seasonal since it said in the article that bedbugs can live up to one year without food. Personally, I'm freaking out. I told my fiance about this last night and he laughed for a good five minutes. I'm admittedly a worrier, and he understands that, but when he heard my plan that included Vaseline, flashlights, and possible legwarmers, it was too much for the easygoing guy he is.
Seriously, though, between the possiblity of bedbugs and the potentially dirty blankets on another thread, my craziness has amped up a few levels. I plan on getting a clean, fresh blanket upon arrival, but I think a request for a large-scale, military sweep for bedbugs might be a little much, even for concierge...
