I had a roll done at WDW a few years ago, don't remember it being THAT expensive.
This year I've ordered lots of mailers from snapfish.com. I pre-purchased developing for 15 rolls of film. I will periodically mail film and some of the pictures will be posted on-line by the time I get home. It will be a few more days before I receive the photos in the mail, but as long as I can see them I'm satisfied.
With prepurchasing the developing, adding $1.99 shipping and $1 for second set...total was less than $6 per roll.
Plus I prefer a matte finish which WDW did not offer at the time.
Not to mention no airport security checks on the way home!
