I was just thinking I would share that on our last two road trips, we stayed at a few Extended Stay America hotels. I think they're a great moneysaver because the rates are super low. They aren't as bad as a lot of cheap hotels, though. They're designed to be no-frills types of hotels for people who are staying for extended periods of time (we encountered a lot of construction workers who were staying for work), but you can stay for just one night. They have little kitchenettes with stoves, microwaves, etc. Plus, they have free breakfast in the morning -- it's simple stuff, like granola bars and muffins and such, but it works.
Just thought I'd share...we prefer to stay in cheaper hotels but don't like to end up in "roach motels." Extended Stay America seems to be a nice compromise. The ones we stayed at were simple yet clean and in good locations. We booked through Priceline and paid $30ish a night in several major cities, like Denver and Kansas City.
