Hotel deals that include breakfast are often a decent value—but be careful; sometimes you're really paying an inflated rate for some cold eggs.

The Hilton Garden Inn is tempting our inner pancake addict, however, with its summer Great Getaway promotion, which promises 15% off its regular Bed & Breakfast rate at US properties—and up to 40% off those B&B rates if you're traveling overseas.

The promo includes breakfast for two and kids 12 and under eat free. The only catch? You have to completely pre-pay your hotel bill, with no freedom to cancel or change your dates.

When we checked out some July dates in a few US cities, we did find a consistent 15% price break. In Savannah, Georgia, for instance, we found  a Hilton Garden Inn in the historic district—with a heated pool and a location just three blocks from the fried chicken and gravy at TV chef Paula Deen’s restaurant. With the offer, you could get a B&B rate of $119 a night for a room with two queens, which is a 16% break on the usual $141 B&B rate. The regular rate, meanwhile, was just $137 a night—which makes the B&B rate a great deal all on its own, since it includes breakfast for four for a whopping $4. Here's a case, if you don't want the restrictions of that advance-purchase, where the B&B rate is happily the best rate on its own. 

To take advantage of this promo, you must book at least 14 days in advance of your stay and travel by September 5, 2011.  Click on the Great Getaway box on the booking page, or mention the deal when calling the individual hotel's reservation line.
