Just used my FITS passes from Aug 7 - 18th. Ordered from Paramount. Went to guest services at the MK on day 1 with the voucher ticket portion, handed them in, showed my ID and my wife's ID, my 10 year old didn't have to show ID (as an Adult) and also had one for my 7 year old son. The three adults had to do the finger scan each time going into a park. Did all 4 parks plus the water parks with no problems. Used the breakfast voucher at Chef Mickey's with no problem either. I also had the same fear of "what if they question where I'm from" but had no problems with that and would use the FITS passes again.
