I know when we went in 2007 we had to make ADR's 180 days out, but the hours were also released 180 days out and Mike had his charts out then. So it wasn't a crapshoot like suggested - everything was at that point. By this point of my last trip (3 months out), I had everything done and planned and had made up spreadsheets with all the info, made a countdown calendar, made pretty picture calendars from the templates on TGM, and it was just counting down the days. Changing the ADR's to 90 days was the first time that the hours were at 90 days as well, as far as I know.
And I'm not as worried since we don't go until the end of the month, but I do think the hours at that point will be WAY different from June and July, so I wouldn't even know where to start. But for those of you going the first week of August, I think the hours, EMH days, Fantasmic days, etc. have been pretty consistent for the last month, and should at least stay that way for the first week or so of August (still summer/peak time). Of course Disney may change all of this, but that's what I would use if I had to guess at this point. I'm hoping by late May, I won't have to guess!
