As far as I can work out:
ATV package = lift pass
Premium package – not needed unless you want to use the other facilities (pool, rink, sports centre). I’m fairly sure you can pay separately for pool access, so this looks a little steep.
coverage = protection, if you want to tell them the make of your helmet, etc (think this is just for marketing)
car make = just for marketing
Signature = confirming that you will have insurance for the race
I just did two registrations simultaneously, but looks like after you’ve completed and paid for the first there is an option to go back and register for “another listing”. Not sure how this will work/where you put in the second name.
Now… anyone any clue what the Electro Avalanche is?
