You take bed bug precautions when you are traveling and when you get home. It's a both/and situation, not an either/or. In hotel rooms the largest threat is the bed followed by other areas highly "trafficked" with bags and/or clothes. Keep your suitcase off the bed and off the suitcase rack unless it's metal. Bedbugs don't like to be "on" moving people in the light, they are attracted to carbon dioxide, hence head toward where humans are breathing when sleeping (the bed in other words). Usually they are brought in via bags, which means they can hitch a ride in folded clothes. Infestations are on the rise in the US, and the bugs are notoriously hard to get rid of, so the best thing to do is to take just a few minutes and a few precautions and don't get them in the first place. I've known two people personally that have had them, one in their apartment and one at their place of work. They were found recently in a nearby movie theater as well. They do happen in Disney. It's just an extra reason I don't unpack at any hotel. And, yes, the bathtub is the safest place. lol
Having said that, I've just never unpacked even before we had the uptick in bed bug issues in the US. I don't view a hotel room as mine I guess, and I'd rather have my stuff in my own suitcase, I know where that suitcase has been.
