Retainer (Volunteer) Question!

So just recently as I got the email that I was accepted to volunteer at this years event.. I have been getting worried thoughts as I would get dismissed due to no matter how hard I try.. I will be late arriving for the Orientation as the earliest flight out to Vegas I can get on Friday is with a arrival time of 11:30am.... Or pay $400 to change it to leave the night before as for my airline I have... Their Standby flight is only good on same day flight and not a Flight that is set to leave the day before....

I am 100% still interested in volunteer as it is a honor and a privilege to do so.... But can I please get a response what are are you guys plans for those that who arrive late for Orientation to Volunteer.... A Response ASAP will be great instead of having to wait the next week or 2 for the next email of the extra details.. and it would help keep this Lalafell on a cool head and not get stressed up over something so silly...

My Default flight I am set to right now is to Arrive 40 minutes later at noon but at that time it be past the Orientation time...

So Again;... Please help me get rid of these worried thoughts I been getting the last few days.... and nights that have been keeping me from sleeping... :(
