Goofy's is my favorite and I go every year for my birthday!!!
BUT when I went last week, I was suprised at the small number of characters that came by our table. The usual Chip, Dale, and Goofy came by and we took the usual pic w/ Pluto, but Baloo was also there and didn't come by. Those 4 (not including Pluto) were the only characters walking around! I knew that they usually have a female character walking around too, but didn't see anyone. Then as we left, they swapped Baloo out w/ Alice. I'd say that that was my least favorite time there, but good thing it wasn't my b-day or I would've been cranky.
I have had that happen over the years. Actually, I have experienced one extreme to the other in character interaction at Goofy's, and everything in between. There have been times where there were so many characters coming by - one after another after another - that I couldn't get a bite of food because I had to constantly be on alert. I know a lot of folks would prefer that because they are paying for the character mingling, but I am paying for an equal mix of good food and some character interaction, so I like to be able to eat. I don't like not being able to relax for a few minutes and eat because there's another critter pr princess coming 'round the bend!! I like a good balance. THEN, I have also had times where Goofy's was very slow and only a couple of characters were making the rounds. One time, in September 2007, literally not one single character came to our table. They must have been having a character staff meeting that day or something. Goofy just ran through the restaurant and waved at everybody, and there were no visits from anyone at all!

Still, it is my favorite place to eat and I continued to go back.
But most of the time, the average trip to Goofy's that falls in the middle of the two extremes includes the visits from Goofy, Chip, Dale, Baloo and whichever Princesses, etc. are on the rotation that day, and then Pluto usually is at the front. I can personally deal with that number of characters. And I also don't mind if the same handful of characters come back to see us again and again because they interact and gesture and draw on the table and act crazy when they have more time to do it and fewer customers to visit. Other folks may prefer an all-out onslaught of characters, and sometimes it
is that way, and still others prefer 'quality time' with fewer characters. Also, the busier it is in terms of number of customers, the more characters there tends to be.
But even if Goofy's is having a character staff meeting or (whatever it was in 9/07) again, where there are absolutely NO characters visiting us at all, I would still be content with the food. For other folks, if Goofy just ran through the restaurant and waved at everybody quickly, I think there would be a mutiny and mass exodus of the customers!!
