My dh says that Mainstreet in the morning, is his FAVORITE part of DisneyWorld. To him, if we didn't do mainstreet the first morning of our disney trip, he wouldn't have felt like he got the magic. He would rather do that than ride ANY of the mountains. (edited to add: He is a HUGE coaster fan, he just feels he can ride rides anywhere, but can't get Disney magic anywhere else.)
So, I am hoping to sneak into a fastpass kiosk, while he ogles the shops...or better yet, get my fastpasses ahead of time (fingers crossed for an offsiter???)
