DL! I went in Aug, not my first trip, I grew up in SoCal. But I had not been in 10+ years..more like 15! We have gone down to WDW so often I had forgotten all the cool stuff at the orginal. Like the flag pole in front of City Hall was a last min thing and was made from a lampost. And Walts Apartment over Pirates...
However, I was there one of the last weeks before SoCal schools when back for fall, 3 days were more then enought for me! It was a solo trip, and I had no ADR's but I still walked into Blue Byoue for lunch. And every other sit down meal I had at both DL and DCA. I liked the themeing so much better at the orinal Soaring!
And the new rehab at Space Mountain rocks so hard! I could not believe how fast and smooth it is. Took my breath away! Almost reminded me of RNRC at MGM.
The Pirates ride is down for rehab, but should be back up by July, and it is worth going just to see it! I have been on this ride in DL, TokyoDL and WDW, and still love the orginal.
You can sit on the steps in front of the POTC ride and see Wishes, and stat put, 'cause in less then an hour after that you are front and center for Fantamsic. OR you can book a Desert party and see both from up in Walts apartment over POTC ride. It is now an Art Gallery.
Keep in mind that Walt had a much, much larger piece of land to do MK then he did for DL. Every thing is so much closer/crowded together. But if you cross the park 7 times a day at DL it is a hole' bunch less walking. And the hotels are very nice. One reminded me of Wilderness Lodge- only more restrained..... a little more Arts and Crafts influe. then WL.
DL Hotel has been re done in the last few years, acording to the info from DL. I was told that most of the rooms have "pixie dust" that travels around the room as a night light. No idea how/when or ? I do know that the orginal rooms were smallish.
We will be there for our DD grad from USC in May. Hoping to stay on site. But if not there are a ton of hotels that you can stay at across one of the many streets. I saw the fireworks from my off site room. And Calif.Screaming was down... hoping it is up! There was an accident some time last July, and with Cal. laws it can/has in the past taken a much longer time to get rides recert.ed for riders....
All in all I think you will have a great trip! It had been 18 months since my last trip to LA/SanDiego and I could not believe how much more traffic, even on a Sat! So take that in considration also.
