Thank you all for the tips. I know WDW inside out, backwards & forwards. We haven't been to DL since 1989. We would be at DL between Dec 27th & 29th. What is not to be missed at CA?
Some DCA rides are also found at WDW and may be of lesser interest to you. But here goes.
1. Soarin' Over California - ride is same as Epcot but the themed location and line are better at DCA giving an overall better experience. Personally I can never get tired of this ride.
2. California Screamin' - IMO the weakest theming of any Disney coaster in the USA, but still a lot of fun. Has a level start like RnR at WDW and has a loop.
3. Grizzly River Run - not as fun in December as in summer, but they do have a reduced setting they use in colder months that reduces getting guests wet. Most everyone including me says this is much better than Kali at WDW.
4. Tower of Terror - does not yet have random drop sequence like WDW but is fun once or twice
5. Aladdin - 45-minute Broadway quality musical that is just fantastic. This is truly not to be missed.
6. Animation Studios - this in HPB and my kids always like to hang out here for an hour or more. Several fun animation and sound experiences.
After you do the above, the second tier will include:
7. Monsters Inc
8. Block Party Bash
9. High School Musical Pep Rally (if your kids are into this)
10. Golden Dreams (worth doing once)
