While the walk to and from Goofys is not that long, dont forget to factor in standing in line to get back in the park when you return. Or waiting for the monorail, if you choose that route. The last time we went to Goofys it was about 2 hours from the time we left the park until the time we returned. That accounts for walking to Goofys, waiting for our table, eating, walking back and waiting in line to get back in. Thats too much time for us!
We are much like Bethy- we have a light, early, breakfast then hit the park. After we have played a couple hours we are ready for a nice big relaxing meal at the plaza. We have had much better character interaction there. I also like that there are people behind the buffet line plating food to reduce the chances that some other guest has touched with their dirty hands before I got to it. Yes, I have issues. LOL!
