Found 2 reports:

They need to take the rooms on each side of it and below and about out of service too to exterminate.

11/30/12. Went home with several bed bug bites after two nights. The hotel has taken the report seriously and taken the room out of service so they can exterminate. I know I did not bring them to the hotel, since I live in a part of Florida where bed bugs are not an issue.
