No limits you get free time with an instructor, tea/coffee etc - Really laid back and run really really well! Kind of bike event, run by bikers
MSV is well run but you can tell its a commercial, cash cow for them and run as such but they are good!
Evening track days are very hit and miss to be honest. I wont do them as I find people are knackered, rushed and poorly prepared!
If its your first time. I'd say save up and do a day that you can take your time and learn the bike etc, then do an evening
