Headed to Celebration this Sunday and recently sailed on the Wonder of the Seas. I will come back and let you know. After seeing Youtube videos and reading comments, the Celebration's rooms seem to be smaller and also certain venues on Celebration are smaller but they have more selections for entertainment, pools, and dining choices which make up for space/crowds. The only complaint I have heard online regarding Celebration's capacity issue are the elevators. There seems to be a long wait and they only hold 9 passengers at a time. Many people choose the stairs where possible.
