I stayed at the Baymont in Jeffersonville for the last meet. It was fine but a bit further out of the way than would be optimal. If you call the Wilmington Inn and tell them you're a ECTA racer they'll take care of you. My room for the next meet is $55/night and just a couple of miles from the track. I'll wager the place you're considering is fine but a bit too far away if you can have as nice a room for the same $$ in Wilmington.
Just for grins - anyone know the airport code for the Wilmington, OH airport? Ours is ILM in Wilmington, NC. I think Delaware has WIL.
