I bet you'll love it! We did! Things are different, but when you walk into the Magic Kingdom and see the castle, you'll know you made a great choice.
We loved the rides at Magic Kingdom and do ride POTC - different doesn't mean worse.
We did miss Indiana Jones and were excited to ride Dinosaur, but were mildly disappointed. The ride follows the same track, but is in the dark a lot of the time. Less theming we thought, which we love about IJ. Make sure you ride MT. Everest - it wasn't ready when we were there, but remember them building.
WDW is a totally different experience. We loved the WDW resort atmosphere - stayed at Port Orleans Riverside. Beautiful theming at each hotel, done up Disney style, with nothing left untouched. It's like one huge resort with its own freeways, shopping, parks, etc. Unlike any other place in the world

!!
Downtown Disney is incredible as well, more spectacular than DL and we loved the transportation from here to there. No complaints about transportation like I've heard on some threads - while yes, it could be crowded, people always made room for those who needed it, and I felt totally safe travelling around by myself when I wanted to go shopping alone, or wanted to go back to the hotel when the others weren't ready.
Enjoy - we did!
