I have really enjoyed reading the original post and all the responses. We just got back from our first DL trip after many WDW vacations. (I've been to WDW around 20 times, and my kids have gone 6-7 times and they're in their late teens). We very much enjoyed ourselves but I'm having a hard time processing whether I can say I like DL better than anything at WDW. In our experience, I would not agree with cast members being more friendly in California; we commented that many of them we experienced were not necessarily rude, but just boredly going about their business with not a lot of joy. Our favorite by far was Drew, our waiter at Cafe Orleans. We had a great chat with him during our lunch there and even stopped back by two days later just to chat with him even though we weren't eating there again. As far as the guests being nicer in DL, I guess I can see that in retrospect, although it didn't necessarily stand out to me at the time.
I felt there was way more "line jumping" at DL, with people moving past you in line to theoretically join their party up ahead. This seems to be more frowned upon at WDW.
We spent two days in
Disneyland park and went open to close both days. Ironically, I suppose when you tack on the walk from the hotel, we ended up walking more those days that a typical day in WDW. We walked over 11 miles our last day. It was fun riding the old Fantasyland rides that I grew up riding at WDW, and really enjoyed being old enough to not pee myself in fright at the evil witch on Snow White. I LOVE Indiana Jones, but I didn't necessarily think the ride was superior to Dinosaur except for riding to the iconic music. Pirates was definitely better, BTMR was better with the effects, and, even though my kids are older, we loved the atmosphere of Mickey's Toontown and agree the queue for MMRR is vastly superior at DL.
We all ranked DCA in 6th place of the U.S. parks. Now, that is based on one day there, and I can't say we had a great experience there. It was probably a rookie mistake, but we went straight to RSR at open, only to find it not running. We waited a bit to see if it would open, but by the time we headed out, with other rides being down as well, by the time we go to Soarin', it was over 40 minutes. We went back to RSR afterwards, as that was our top priority, as the line was posted at 45. It ended up being twice that, since the ride went down again while we were in line for awhile. By now, it was basically lunchtime, and after lunch, we decided to try GRR. We got about 20 yards from the loaded area when the ride stopped. After waiting about 15 minutes, they told us it was down and we had to leave. So, we decided to try Webslingers, which again was listed at 45 but ended up being 80. So now it's 2 pm and we've done exactly 3 rides. We headed over to Monsters Inc, and it closed as we were walking up to the queue. Needless to say, we were frustrated at this point. Now, the day got better. We loved Incredicoaster. We ended up getting to go in the G+ line later for Monsters, even though we didn't have G+ due to a very kind cast member. We tried GRR again later, and it closed down when we were in line again, but they gave us a MEP so my kids got to ride Incredicoaster again. Our older two loved GOTGMB. We ended the day nearly dying on GSS and watching World of Color.
I would definitely visit again. We live in Illinois, so we sometimes drive to Florida, but we wouldn't to California. I think it's hard to objectively compare a place you visit once to someplace you've grown up loving for many, many times. But I've very thankful we got the opportunity to visit.
