This is a topic that comes up often on this board, if you search through the posts you will find thousands of replies that indicate just how "worth it" a trip to
Disneyland is!!
The two parks are not the same. They have some similar features and attractions but if you go to Disneyland expecting sprawling resorts and transportation options between them, you won't be able to appreciate Disneyland for what it is.
It is the original. It is where the dreams began. Walt himself walked down main street. Everything is closer together but not "cramped" at the end of the day you don't have to feel exhausted from trying to see it all (although I assure you there is plenty to see). Southern California is BEAUTIFUL you can combine a trip to Sea World, the San Diego Zoo, Hollywood or Universal just to name some destinations within a 2 hour radius. Then there's the beaches, wow! That is, if you even want to leave Disneyland.
You can walk across from Disneyland to California Adventure. Not walk like forever, like a five minute or less walk from entrance to entrance. Accomodations, you can spend as much or as little as you like and you'll be within a 20 minute walk or a shuttle ride away.
And with the 50th anniversary next year, I can't imagine a better time to say that "you were there".
