This may get closed down if we have too many on the list. When spots come available, you will receive an email notification to Accept or Decline and will have a few days to confirm before we cancel your waitlist spot and move to the next person.

All credits from 2020 are loaded into your Ultrasignup account and you should see it at checkout. If you believe you have a credit from a previous year, please forward the original credit notification email to (we don’t track older credits).
