I agree to the sticker shock. There is a thread somewhere that people were posting their per person rates. I stopped reading because it was way too depressing compared to what we are paying. If you look at rates 3 weeks later, the price plummets by 40%! We are also at the mercy of Spring Break, and I work for the schools, so I don't have extra time off.
We have a family of 5, as well. One room is a 5B. Instead of connecting rooms, our second room is an inside stateroom across the hall. This helped with the cost by almost a grand. That option, of course depends on the age of your kids.
Good Luck and do what works best for your family. My kids and DH all chose
DCL over a Hawaii trip! I keep telling them I am spending their college money!

...and Christmas, and birthday...
