I just started to consider this.
I've started a Photopass share with 2 other families on another site I frequent. Neither of them has been to WDW before (or at least not since they were kids.) I prepurchased the CD at $99, and figured that each of us would pay $33; my husband will mail them a CD of their pictures.
But now, 2 days before my trip, I'm starting to think about "plus." We'll be on Space and Splash mountains, Buzz, Rock'n'Roller, Dinosaur, Chef Mickeys, and Hoop De Doo. According to what I've read
http://wdwnewstoday.com/archives/9081 I think the photos from each of those locations would be included, right??
Can I ask: how much would it cost to upgrade? I'm thinking of upgrading for myself, and just letting the other 2 families keep what they've agreed to (of course, I'll run it by them before doing anything.)
Does my reasoning make sense??
