I tend to agree with the others here - we were very, very fortunate to have the opportunity to dine at Club 33 to celebrate our 15th anniversary almost 5 years ago, and at the time, we took our 2 kids, a girl, who was 5 and a half who has the patience of a Saint, and our boy, who was 11 years old, who doesn't always have patience (ok, rarely has patience) but I educated him on Club 33 ahead of time so he would know how special it was, and both kids did really well. It was hilarious when one of the servers dropped a small desert on the floor, and Tuxedo Mickey began pointing to it, shaking his head in an 'oh no!' motion, basically making a big commotion over it, and our kids really enjoyed the character interaction. Pluto was awesome, too!
Would I go to Club 33 with 3 younger kids, including a baby? My bet is your baby is going to be the easiest to entertain, while sitting. 2nd and third children tend to be more 'easy-going' by nature. My concern is for the 2 younger boys, and put all 3 kids together, and it could be a recipe for trouble. If this is not a once in a lifetime opportunity for you, as it does not seem to be, I would wait to take the kids until they are older, and enjoy the quality time with your spouse. I have never - ever - had a more enjoyable cup of coffee than I did there. The food was perfect, everything was awesome. You will have such a great time there, enjoy!!
You have someone there who can entertain the kids -maybe Grandma & Grandpa would enjoy taking them to the build a bear or that car building place in Downtown Disney. (?) You are really lucky to have someone with you that you trust, who doesn't mind keeping the kids.
In any event, whatever you decided to do, have a great time!
