I finally looked through my videos I took of the ST Octane Academy. My camera started running out of battery I guess right at the Urban X course stuff. I never use my dashcam on battery but it looks like it records partial clips and shuts itself off when it's low on battery... Even though it kept recording partials until I realized it wasn't recording correctly anymore, weird. Anyway, it did at least capture all the track stuff, including the instructor hot laps. So once I get back home I'll upload all that and post it here.
The Comfort inn is nice and if you use the promo code on the st octane website when booking online you get a decent amount off and it applies for multiple nights. It's really close to the track too so you won't be late as long as you wake up on time. You won't have to deal with rush hour traffic in SLC. Some people stayed in SLC because they were doing other stuff there before or after, but there were a decent amount that stayed at the Comfort Inn on my day.
I don't do night life so I don't have a clue. My night after the track was driving out to the salt flats to catch the sunset. That was well worth it to me.
