Hmm... i am wondering how 2010 will look at DCA.
Silly Symphony Swings will be open. World of Color will be open. Little Mermaid still under construction. The main entrance will be under construction beginning when?
What's new in Walt Disney World? nothing. But since you haven't been there in awhile, everything is new to you so there's something about that. But there's also something about Disneyland too.
If you take your kids to Disneyland first, they will have a great time. Then when you go to WDW, they'll see the bigger castle and the more parks.. it will be like a step up for them (even though it really isn't).
I'm sure it'll be fun either way.
