Go to
www.disneyland.com They have schedules for the days that you will be there. You can look up parades and other stuff like if any rides will be down or openings of new rides.
The Finding Nemo ride just opened a few weeks ago. I just got back from DisneyLand at the end of June. EVERYONE rushed to the Nemo ride first thing in the morning. We took advantage and went the other direction and rode several rides with no line at all!!
One of our days, we did go on Nemo, but first thing. On the days we were there people waited FOUR hours to see this ride!!! (No FASTPASS available).
We did not care for California Adventure. It is more amusement parkish (IMO). Lots of rollercoasters and such...not for our crowd with small children.
We stayed nearby and were able to get to the park walking an about 5 minutes. The advice about taking a break is good!
You will not want to miss Fantasmic! It is a water show at night. People start staking out seats well beforehand. You will want to bring a blanket to sit on. Right in front of the water in FrontierLand (I think) is where you want to go. I put a blanket and my husband down about 2 hours before the show and we had great seats after our ice cream trip!
There is a restaurant that you can make reservations (for an extra cost...%0 bucks, I think!) and they have really good seats for Fantasmic, but you don't really need to do this.
There are great parades and plenty to do! I found really good food choices (fruit and veggie stands, etc.) We also brought a fair amount of healthy snacks in our backpack.
You might want to check out
www.mousesavers.com and maybe a DisneyLand book from the library (like Froder's).
Be prepared for crowds and a busy park, but it is a wonderful place! I have more, but I'll stop for now. Just let me know what you would like to know!
