Can anybody tell me what is open during MM in disneyland? Are the princess available? Can you do BBB with the castle package (meeting the princesses) that early?
Generally speaking, most of Fantasyland and Tomorrowland are open during MM...including Matterhorn.
However; I don't know about BBB (probably not?) or the Princesses being at Fantasy Faire that early.
I haven't tried BBB either, but based on the Disneyland.com webpage, it appears to be open during MM. It does recommend making reservations, so you should be able to figure out if takes guests during MM/EMH. Fantasy Faire does not list EMH/MM hours, while the other FL and TL attractions do, so I'm inclined to say the princesses are not meeting guests during EMH/MM.
I believe you were asking about TS meals on another thread, and planned on going to Ariel's Grotto. If you do a meal there, you'll meet several (5-6) princesses without having to wait in line during precious park time to see them. When we went last year, we met Ariel, Snow White, Aurora, Tiana and Belle. Each one comes around to your table for pics and autographs, etc.
