Hmmm. This sounds a lot like me the first time I came to DL after falling in love with WDW. That was back in 2006.
I can't speak to rides breaking down, because I haven't experienced that too much at DL. No more than at WDW. In fact, I've seen breakdowns more at WDW - BUT!!!! I've spent a lot more time in FL than Anaheim.
For
Disneyland Hotel, I'm hoping that you're wrong. I'm a big fan of WDW hotels and I know that Paradise Pier couldn't really stand up to even the AllStars of Florida. That's why I saved some money on our last trip and stayed at the HoJo. I'm staying at DLH next month and I'm hoping that it takes me back to that WDW feeling I get at the Florida resorts.
When it comes to cleanliness, Disney does it best. That said, I did notice on our last trip that the bathrooms tended to be untidy most of the time. Don't know if I kept timing it wrong, showing up before maintenance or after some messy kid, but I did see this a lot. As for the parks, they were clean. Didn't notice trash lying about or duct/duck tape on any rides (we didn't ride the Matterhorn). But I didn't go during the craziest busiest time of the year.
AS for going back to WDW, I'd like to do the same thing. But costs are preventative to fly out there, plus FP+ just makes me shake just thinking about getting up early and trying to book FPs for an entire trip. Ugh. Even with 4 marvelous parks, great food options, and fantastic resorts, FP+ is like a magnet repelling me away and keeping me in CA. What are your thoughts about that?
