So I walked into the Hilton yesterday and saw ear plugs on the dresser. An odd accessory I thought since Hilton is so stingy about their other give aways (in some markets they don't even give conditioner any more replaced by "conditioning shampoo" only).
In the bathroom they have details about the recycling program.
It wasn't until much later that I saw the noise disclaimer. Either Hilton cares, or noise is a real problemQ
