Are you wanting to make some passes Fri night? If so, somebody should be at the track to check you in if you're pre-registered, so you don't have to pay for grudge racing.
But, a lot of us will be at the Cruise-In by that time, at Fuddruckers on Noland Rd. Also, the parking lot party will just be getting started. If I were you, I'd just check in at the hotel, check for the parking lot party and then head over to Fudds. There'll be plenty of chances to race on Sat.
Also, the hotel is right on your way, at exit 21 off I-70 as you're coming into KC.
