Lots of Hilton family hotels all over the country, including reasonably priced chains such as Hampton Inns. Not sure how this compares with the other options folks have mentioned, but you might want to check it out.

I believe that some chains within Hilton might include free breakfasts for all guests. Regardless, if you make Gold status through enough nights or via getting a Hilton Surpass Amex card, breakfast is included in all Hiltons.
