I don't think it is an issue, but it is a cost.
I guess I'm wondering how it will all fit in?
AHRMA generally operates a "two race" program at their events. If you race F500, you race it twice, once each day. That has made going to some events attractive as you're getting in "two nationals" for each event. I can't say that I know how AHRMA will be setting up their event for Daytona, but, if most championships in their series are sewn up before Barber the weekend before, I'd have to wonder how many would take the extra time off work to do Daytona.
Just thinking out loud...
