Wowza! I'm not usually one to complain about costs, but some of these hotels are out of their mind with what they are asking. Maybe I was spoiled with super cheap hotels last summer. Some of them are also including tricky cancellation policies.
An example, the Courtyard in Kennesaw wants $270/night for the cancel anytime rate (compared to $220/night with the "you are screwed if you need a change" rate) for the first weekend in June.
