A couple of years ago, I was able to get a solo table after an hour wait. I would imagine it would be a little easier now that the restaurant has expanded. Don't get your hopes up though. I've heard that most people aren't as successful with walk-ups.
Have you considered an alternate character breakfast??? I loved GF's and crystal palace's character buffet, even though it didn't include the fab 5. I get my fab 5 fix at the Character Spot in Epcot
YAY! You'll be happy with your choice, I'm sure. I've eaten there on several occasions and have always enjoyed the experience. I can't say the same for CM...
