I have learned my lesson when it comes to staying in pet-friendly hotels. The room we were assigned had a flea infestation. As soon as we entered the room and walked across the carpet, dozens of fleas were on our shoes and legs. Before we realized what was happening, we had tossed down our backpacks, luggage and the fuzzy blanket my wife had been carrying. All of our stuff had fleas on it.
We gathered our belongings and exited the room as quickly as possible. The front desk clerk was apologetic and gave us a different room. I asked for a room on a floor that doesn't allow pets. Instead, he upgraded us to a suite on a pet-friendly floor and told me they don't normally assign the suite to those traveling with pets.
For the rest of the night, we were still dealing with fleas in the new room. It was impossible to say whether the new room also had fleas or whether we took them into the suite with us. Regardless, with certainty, that room did have fleas by the time we checked out a day early the next morning.
