I would have loved to find In and Out by Disney. We did everything in walking distance and I never noticed one. We did hit on when we were in Valencia. Yum, yum, our first time at one.
I heard that if you are going to the Character Warhouse in Fullerton that it would be easy to go to an In and Out that is very close by..just one more option!
I plan to go to Character Warehouse via city bus, stop at nearby grocery store for snack items and lunch at IN and Out.. take taxi back to Ho Jo's. It's something to do when we get there in am - waiting to check into hotel.
