We are also huge WDW fans but are HUGE DL fans as well. Please do not compare the parks. WDW is sooo much bigger and there is sooo much more to do. Having said that please take in DL completely.
I have said before I actually prefer DL over WDW.
The fact that Walt himself had a hand in Disneyland and that he personally walked the streets of the MK for me is enough. DL has a much more cozier feel to the park than the MK at WDW does.
Enjoy it
