I never thought of that either. I guess with the ships not ready for a couple of years now. Maybe they will have ships dock there on different days.
The problem isn't really the day that they dock as the fact that the new ships will be larger themselves and carry more passengers. There will be more people streaming onto the island no matter what.
According to http://www.passporter.com/articles/disney-cruise-line-new-ships.asp , the Magic and Wonder hold 2,400 guests each. The new ships will each hold 4,000 guests. Not quite double the number of people... they're definitely going to need more room on CC.
Wow, I had never thought of that. That is an excellent question. They will definately have to do something to accommodate those additional people. The family beach gets pretty crowded.
I imagine they will not fit so would therefore have to close it to dredge more, or have another docking area. Does anyone have Google Earth so we can spy on what they're doing?
Besides not being updated in real-time, the resolution in areas such as CC is nowhere near as good as urban and residential areas.
