We took our first DL trip this past June/July and we loved it!!! We went to San Diego first, because we were afraid that it might be a bit of a let-down for our DD(6) after being at DL. Our 3 days in San Diego were fantastic: first day sightseeing, second day Seaworld (we liked it more than Orlando), third day the Zoo. On the fourth morning, after breakfast, we drove our rental to DL (about 1 hour and 45 minutes using Mapquest's easy directions - very direct route). We had decided to stay at the GC and were we ever glad! DMIL, DD and I checked in while DH and DFIL drove to the airport to drop off the rental. By the time they returned, we were checked in and were exploring the stunning lobby (they were only gone about 40 minutes). It's a beautiful resort, Downtown Disney (better than DTD in WDW in our opinion!) is literally outside the door, and it's a 5 minute walk to DL and CA.
I agree with the poster who said Blue Bayou is a must - what a beautiful ambience and the food was great! Kids get a paper pirate hat (their menu) and they'll love seeing the boats float by. Also high on our dining list was Ralph Brennan's Jazz Kitchen in DTD. They seat you upstairs on kind of a wraparound veranda, and the combination of good food, a warm breeze and the view makes it a very special meal. The GC's character breakfast, in the Storyteller Cafe, was very enjoyable, with Chip & Dale, Pluto, Kenai, Coda and Turk walking around. We also enjoyed the character breakfast at Goofy's Kitchen in the Disneyland Hotel (about a 10 minute walk from the GC). It is comparable to Chef Mickey's, with lots of singing and dancing, and many standard as well as interesting food choices.
The dates that we visited DL and CA were from June 27 - July 1, and although it was busy, we saw everything , sometimes 2 and 3 times, thanks to the touring plans in the Unofficial Guide to DL. We arrived early for the EMH (we were only allowed once for the visit - don't know if that will be the same this year), and were able to leisurely stroll through the parks while following the plan (2-day plan for DL). By 10:15, we had seen all of Fantasyland and stopped for a nice peaceful breakfast, while the park filled up and most people were now running to Fantasyland. So, we follwed the plans and headed to other sections of DL. The next morning, we arrived before opening and were able to see everything else! I can't recommend that book enough! It does get packed at night, though.
Well, sorry this was so long, but we had a great time and I love sharing it! You'll have a great time, too - enjoy!
