Everything in the Dells is within a 10-15 minute drive. There are signs and broucheres everywhere. I know that there is one road the connects to just about everything, so you'll have no problem finding anything. Like I said, every resturante or hotel you stay at will have brocheres and directions.
About the costs, I'm not sure, because the last time I was there was two years ago. You just missed me, I'll be heading up there Friday.

There is no such thing as a stupid question, just stupid people.
