For those who have been there, please share your experience
What time did you go?
7:10 AM on an early entry morning. We have APs and weren't staying onsite, so don't get MM anyway. We had multiple days at the parks so decided it was worth it to spend one of our early mornings this way.
What was the best thing to eat?
The made-to-order omelets. The boys liked the mini Mickey waffles as well.
Do you seat yourself? Where are the best seats?
Inside or outside?
They seated us. We have eaten outside there often when we get the counter service food there later in the day, but when we went for the character meal, we were seated inside and liked it. When the restaurant started to fill up more by the end of our visit, it did get a little bit loud though.
We stayed for the full 90 minutes they allot you.
Do you go enjoy the park early on a MM and then eat or eat early, then play?
I think this depends on preference and how many days you are in the parks. If you're only there for 2 or 3 days, you would probably do better to use the early mornings for riding and collecting fastpasses and eat later in the morning. If you're going to be there for more than 3 days, you could certainly spare a day for an early morning meal, especially if you only have one early entry available to you and have already used it but it's an early entry day again.
Do they do photos like GK & SU!?
They did photos, but it was not a photo with a character, just a family photo right outside the restaurant before they seat you.
We are a group of 9 adults & 6kids (3 families of 2A & 2k each, and 3 grandparents) should we sit together or maybe just get tables close to each other?
You should definitely call Disney dining to make a PS. Check if they will accommodate that size party all sitting together. I think they might be able to...there was a very large group behind us when we went last month, at least a dozen people and they were seated together. It seems like you would have more fun all seated together. If not right together, especially if you want to be outside, you should be able to get a group of tables located near each other.
