Last minute vacation suggestion? midwest/drivable!

[tchariya]

ok so i'm off for a week next week but have no idea where to go to get away.

1) I'm in the Chicago area
2) destination should be drivable or Amtrak/train and warm!
3) looking for relaxing...not really wanting to sight-see the whole city
4) 2-3-4 nights
5) camping? casino? spa? pool?

cost...well not looking to blow so keep it $100/night for accommodations


I might consider Lake Geneva again...but that is not too high on my list
