Have done this two years now. The experience is not great for the money spent. The amount of time driving on the track is minimal. You are limited to the speed of the driver in front of you. So, if you are behind a slow driver that is your experience. It was very disappointing, I tried it a second time but still was stuck behind a slow driver. If the slow drivers could be isolated and go at a different time that would help. Too much money for me to try again for speeds that I do on the way to CA.
Regarding the other items during the experience, skip the go carts, not fun and very uncomfortable. The other things are fine but seem to me to be filler.
