No one likes being stuck with the inside stateroom on a cruise ship. The only thing that's right about it is the price. But there's a reason you pay less for those cabins. No view.
Disney has tried to remedy that on the Dream by building "virtual portholes" in interior cabins. These porthole structures above the bed give realtime video of what's happening outside the ship, so it's like having a "virtual" window. But this is Disney, so there's a touch of added magic in the form of animated characters dropping by the porthole every now and then to say hi.
