Yup - Disney fuzzy math seems to extend to Disney fuzzy plans. I'm imagining the first afternoon at MK - DH gets tired/grumpy an hour after lupper, and decides to go back to the hotel. Then I can stay as long as I want at MK, versus moping around HS for a couple more hours. Since I didn't get hopper tickets this time, I also don't want to waste potential park time. Who knows, I may be tired myself, but there are definitely more options according to Disney fuzzy logic to switch to MK for day 1.
On other news - rough weekend at work. I'm down half a bottle of wine and the leftover Christmas goodies are taking a hit!
