Agreed. And that walk is mostly without shade. I would not walk from TTC to MK. The walk from Contemporary is not bad at all.You do NOT want a 30 minute walk to MK, especially with what you have in front of you. In front of you means more walking for hours and then a 30 minute walk back. Park at TTC, monorail. I would definitely not do that walk. Only if at Contemporary.
EDIT: And, there is no reason for TTC for AK or HS. They have their own parking lots.
