We were there last week, and used Touring Plans, and planned the week on Sunday based on their crowd calendars. Chose Epcot Monday as a 'best park', and our plan was correct to the minute. 11 attractions/rides from 9-3:30 with an hour for lunch at Via Napoli. Next day DHS was off just a bit, but our other days at MK and AK were right on track. Am a total believer. Hit everything we wanted to hit, so we could spend our last 3 days taking our time in the parks we wanted to revisit, and check out new things. Based on our experience, I'd say they work!.
