Oregon Coast Casino trip

My plan for the last week of June is to stay at three Casinos along the Oregon Coast. Start out at the Chinook Winds Casino in Lincoln City, then drive South to Florence and stay at the Three Rivers Casino then South to the Mill Casino in Coos Bay. The plan is to take a week and stay in the FREE lots at the Casinos. We have several places planned to see along the way. It's been a long time since we have to some of these places so I think a week might not be long enough but my wife thinks we should start with one week planned and see how it goes. http://www.casinocamper.com/Oregon.htm for a list of Oregon Casinos.
