We LOVE Drury Inns, although I think they are more in the Southeast than a national chain. Free full breakfast buffet(eggs,meat,etc),free popcorn and soft drinks, and free evening appetizers and cocktails. All this and we have payed as low as $54 with them. We stayed there in Greensboro area and Atlanta.
Also,while it's a timeshare resort type thing rather than a hotel, we have found that renting through an owner of Diamond Resorts (found them on ebay,and stuck with them for future trips) has been very economical for us,especially offseason...we use them for Grand Resort in Orlando and Powhatan Plantation in Williamsburg...we have been able to get extremely nice 2-3 bedroom condos for the price of a Hampton or less.
