I agree if you have a problem with a property that you should bring it up right away. Sometime with bedbugs though, you may not get attached the first night or it has taken me a day or two before I've noticed what I'm scratching it.

I guess I'm not sure I'd ask for full compensation for the stay, but someone - either my employer or Hilton WILL find a way to reimburse eradicating them from my home. As my lodging provider, keeping the bedbugs out IS Hilton's responsibility, the same as it is for ants, centipedes, fruit flies, etc.
