Why couldn't I have been one of the 600 Million who got to visit TDL/TDS? I now have 600 million more reasons to feel as though I have somehow failed the themed entertainment industry by not visiting what is considered to be the best themed resort in the world. Not to mention the fact that there are 600 million more people in this world of whom I am quite jealous.
I wouldn't be surprised if it becomes the most popular attraction in the Magic Kingdom.
Also, unless you're staying at a resort accessible through the International Gateway, you still have that long walk back to the front of the park.
