First let me say we love to package our vacations with other things in California. We have done San Diego (which we love), San Fran, Monterey, and Yosemite NP (which is absolutely amazing. We have also done DL just by iteself. I think the perfect one is 5 full days. We usually do 2 at DL, 2 at DCA and one day to just relax at the hotel pool, downtown disney, and go to the ocean. I wouldn't do Hollywood. It is not worth it at all. The last vacation we actually did 6 days and took a sunset cruise out on the Pacific which was amazing. You can catch these for about $15 a person from Newport. The more time you have the more leisurely you can do the parks. It is sooo important to do the little things at
Disneyland. For instance:
All of fantasyland including Storybook Canal and Casey Jr.
Golden Horseshoe with Elvis Billy
Ride the Lilly Belle train car
Fantasmic!, Fireworks, and Parades
Walk thru Sleepy's Castle Dioramas
Ride IASM at night
Eat at Plaza Inn oustide
Swing Dance at Carnation Plaza on Saturday nights (Date Night at Disneyland)
Do jungle cruise at night after you've done it in the day
At DCA
Aladdin (twice!)
Toy Story
Grizzly RR
Screamin'
Soarin'
Monsters Inc
Silly Symphony Swings
and most definitely....
World of Color
The fun thing about more time is it gives you more chances to find the fun places in both parks that people don't mention like the Animation building in DCA, Grand Californian Chaisse lounge chairs, Downtown Disney in the night when the bands are playing, Disneyland's marching band in front of the castle when the characters come out, and so much more.....
Have fun planning and if you have any more questions feel free to ask. Congrats on your decision by the way to go to DL.
I agree with the above poster that said to park hop. It really is so much fun and so doable!
Remember there are as many rides and attractions in two parks at DL as there are at four parks in WDW.
