It’s miles away, about half way round the course ! Sorry to be brutal but what you’ve done by staying in Morzine with a Les Crosets entry is pretty non-sensical (stronger words apply)
Your big problem will be that you have to get to Les Crosets to collect your registration pack. If you tried to ride there (buying pass from Morzine) the registration would be shut by the time you got there. The “docs” you have right now is just an email, the proper pack with your number plate, freebees, lift pass will only be available in Les Crosets
3 options
1) take @deadkenny’s spare Morzine entry (doesn’t help your mates)
2) get up at the crack of dawn and drive with bikes to Les Crosets, register and start/finish there (just checked Google it’s a 1.5hr drive)
3) buy a PDS pass and just ride the course with no number plate, free food, etc etc
