One of our favorite restaurants is Marrakesh. We ate their on our honeymoon and we'd eaten there every trip since.
We skipped it last trip - just couldn't fit it in. It was on the plans, but we switched to Jiko last minute.
Didn't miss it. Jiko was good, and it was nice to do something new.
My husband went back with his brother, and they made time for Marrakesh. And he said "it was OK, but I'm glad we did something different."
I suspect I'll talk my DH out of Le Cellier next time....which has been a must for two trips now. Its good, but there are better steaks at Disney and more restaurants to try.
Our family tradition is the Ohana character breakfast. But I'm on the edge of deciding next trip we will do something different. I think the thing about having traditions dependant on Disney is that Disney changes things - we like the Ohana breakfast - but a prefer a tradition of "a" character meal, not a specific one....that way, if Ohana is closed for a remodel during one of our trips, I don't have a brokenhearted family.
