I used them for our week long stay in November, more to help me get a grip on how much we could expect to get done in a 2-hour period at, say, DHS. Could we make a specific show if we wedged a ride on StarTours in first? It was helpful because it helped me set my expectations. That said, I think the personalized plans can still be off considerably -- I've got some for a upcoming trip and it's calling for rope drop wait times that are twice as long as I think they should be, and they don't account for the fact that rope drop often occurs before the posted opening time. But, I make notes after the steps where I think they'll be off, so I can add in things on the fly without having to hem and haw about it for too long.
