Although I am going to book Trattoria again for September. My sister prefers Trattoria (steak and eggs).
It would be a long walk from YC - but I suppose it is walkable to Fantasia Gardens. I love Winter Summerland - which is over by Blizzard Beach. I have always been able to walk up to Winter Summerland, but in my experience Fantasia Gardens is a little busier (I assume because it is closer) and it is best to make a reservation there.
