I've seen these signs at a few Hiltons, and they do appear to be deceiving.

But how often can you park at a regular Hilton for free? Rarely.

I always get a chuckle out of places like Atlanta where there is a Hilton, a Hampton Inn and a Hilton Garden Inn within two blocks of each other. Hilton has valet and self parking to the tune of $14 a pop. 2 blocks away you park free at the other two properties.
