When we go to the parks, we don't mind standing in lines, as long as they aren't more than 30-45 minutes. We stay enough days, usually two weeks, to arrive at opening, early opening when we have DVC reservations. We go to the rides with the longest lines later in the day, like Remy, Frozen, Rise, Mickey and Minnie, Seven Dwarfs, Tron (I don't ride that one), and Flight of Passage.
We were aghast at the line two weeks ago for Kilamanjaro Safaris after riding FOP first thing. That was unexpected. Expedition Everest had maybe a 20 minute line.
We were pixie dusted, when we took the twins to Little Mermaid while the kids rode Seven Dwarfs. It was basically walk-on, and the cast let us go four additional rides, total of 5, because each time we tried to get off, Olivia (twin) had a major fit. Seriously didn't want the ride to end, until she was done with the fifth ride, when she started crying for her mama. That was weird. There is no explaining two-year-olds. Terrible twos!
Fall break for a lot of schools is that week in October that used to be Columbus Week. I recommend never going during that week.
When Disney got rid of DAS for anyone who requested it, and yes, this was happening, I think it was a wise move because lines were much longer with Lightning Lane being busier, a lot of people were taking advantage of it. I do see people who are being denied the pass and should probably get DAS. It's very subjective and depends on who you talk to. It seems that only children with severe disabilities are getting DAS.
Just being in a wheelchair is no excuse to expect DAS because the lines will accommodate a wheelchair. We did talk to a man with a colostomy bag in a wheelchair who used to get it and no longer does. He lives in FL and doesn't plan to go back after his AP expires. He and his wife were shocked that he didn't get DAS. They tried Lightning Lane one day. They decided it wasn't worth the cost.
