To be completely honest, and I will probably get bashed for it, I prefer the original in California. We (me, husband, 8 year old son, and 5 year old daughter) just got back from a week at WDW in early June, and sure, there was a lot to do/see, but I will take California DLR over WDW any day. We live in Texas, so we're kind of in between both places, so cost is about the same. We decided to do WDW this year over DLR because SWA had such cheap flights between HOU and MCO, I just had to go with it. We also wanted to spend a few days up in Amelia Island.
However, if this is something on your bucket list, and you can manage it, I say go for it.
