Hi Ryan,
I have some good news and some bad news, and then some good news.
The first good news is that Snow White greets guests near the Germany pavilion at Epcot. Weather permitting, she does this every day. Grab a copy of the free Times Guide when you enter the park to see her exact hours during the time of your visit.
The bad news is that the dwarfs rarely greet guests in the parks these days. Unless there's a special event going on, you're unlikely to meet the dwarfs.
The other good news is that there IS a special event going on at Walt Disney World in October - Mickey's Not So Scary Halloween Party.
During the past several years, the only place to meet the dwarfs has been at Magic Kingdom evening parties such as MNSSHP and Mickey's Very Merry Christmas Party. The exact character line-up has not yet been announced for 2014, but if they follow the 2012 and 2013 patterns, then you'll be able to see all seven dwarfs with Snow White at the Halloween Party. The
party requires a special ticket, which is available for purchase online.
Fingers crossed that your travel dates coincide with the Party!
Please let us know if you have additional questions. We're happy to help.
