I just returned from a 6 day visit to Walt Disney World and used custom touring plans, along with the Lines app, for my entire trip. The wait times for the attractions on the Lines app were very close to what the actual wait times were, although on a couple of days the parks were much busier than what Touring Plans forecasted them to be. The only “issue” I had during the trip was with break times for meals, at locations outside of the park I was visiting. Since the restaurant was outside of the park, I couldn’t use the “Meal” button when designing my touring plan for the day, and I had to set them up as “Breaks”. So during the day, Lines was very fluid in the time that it suggested for the break, as it was trying to work around shows. Unfortunately with ADR’s I couldn’t adjust the time of the break to match what Lines was recommending and I had to manually adjust the touring plan.
I also used the advance room fax service, and got the room right next to the one I had asked for.
All and all it was a great service, and I won’t hesitate to use it again on my next trip to the World.
