We're in the same situation (family of 6) and it took me a long time to accept that reserving two (not inexpensive!) rooms was our only on-site option. If it's any consolation, after a while the idea of 2 rooms did kind-of grow on us and I'm looking forward to our having that much space.
We booked at our first-choice hotel (PB) and tried to balance it at least somewhat by using the stay more save more rate, booking standard view rooms, knocking out going to Blue Man Group, using a PIN (received via e-mail) for dining credits at the hotel, and planning to either bring some snacks with us (like granola bars, goldfish, etc) and/or placing a delivery order with garden grocer.
