Unfortunately none of the princesses have a "regular" schedule for Akershus....and they can't even tell you at breakfast who will be there for lunch/dinner later the same day. They say they don't know.
BUT....having done Akershus because it was the ONLY place in all the parks that you had a chance of seeing Ariel with legs, lol......and we got lucky and she was there, whew......I can say that I'll not be doing that restaurant again. The food was ok....service was rushed by polite and attentive (when you could grab her attention, lol). BUT....what I felt we were REALLY paying for was the Princess interaction. And it was horrible. Don't get me wrong, the ladies themselves were marvelous, but they had soooo many tables that they had to get through that they swooshed in, talked while they signed your autograph book, stopped the chatter as soon as they'd finished, lol...pulled the kids close for a photo, blew kisses and were gone. Yeah, that fast.
If you have a child who wants to spend a few minutes with Jasmine.....head over to Morocco (you can call and ask their hours ahead or ask at the gate...they are there for several hours each day, taking short 5 minute breaks about every hour). We went to Epcot probably 10 different days in our month long trip, and we always saw Belle & the Beast near France...and Jasmine, Aladdin and Genie at Morocco. They have a little sidewalk area in front of the country but up against the waterfront, and that's where the Princesses always were. We went for photos at least twice that I recall....and both times Aladdin kept up a constant banter with the kids, asking questions about their stay, and about their wishes (what would you wish for if Genie would grant you 1 wish right now)....Jasmine was a bit quieter, but when my girls talked to her, Aladdin politely stopped his chatter and they got some quality time with her, talking about Raja, lol. Genie of course doesn't talk but he got in some teasing and hat stealing too. And was big on the hugs! MUCH better interaction, photo ops are better too, and it's soooo much quieter than the restaurant (where we often could hardly hear the princess speaking right at our table!).
