We were at WDW last week and there basically were no lines. Every time I saw a person with a dream fastpass I got a little jealous, but then thought, "big deal" most lines were well under 10 minutes anyway. I still wished I won one, though.
Our family won Dream Fast Passes in Epcot last week. Everything was so quiet that we didn't have to use them except (get this) Maelstom!!! Seriously!!!
