I know I can count on the fine folks here at FT. I'm traveling in early July to FRA and need to get over to NUE for another leg of the trip. I'll be with the wife and kids as well as Mom. Any ideas as for getting from one airport to the other and the cost for 3 adults and 3 children?

I'd prefer to take a shuttle or taxi(s). Renting a car is my last resort because I don't want to have to drive while my brain thinks it's 5AM in unfamiliar territory. Thanks, all.
