Bruce,
Are you drivng the Viper and are you thinking about trying to make it in one day from Omaha, or finding a stopping point along the way? As I am in the Quad Cities/Davenport, IA, I was planning on making it a 2 day trip and stopping somewhere near the western border of NE.
I booked my room at the Grand America since that is the host hotel although it appears that the "Little America" is just across the street and a little cheaper.
C'mon spring!
