All the trackday providers provide service with a special twist. Z2 set the standard for instruction at trackdays and the special events and others raised their service. K@TT has always set the bar for safety and trackside services. We riders benefit from the competition. I don't understand why people rag on providers, they are bending over backwards to make us happy. Most smart people don't waste their time slamming McDonalds on the internet, if they don't like the food, they just go to Burger King.
One thing I've never seen, though. TDP providers might consider a client satisfaction survey after each day, it's part of business for most industries now. Gives people a place to vent without having to talk about why their anus is tender on the web.
