It might be silly, but I just booked a room downtown near Centennial Park. We're going to the aquarium one day, and the children's museum te next. It's only a 45 min drive each way(depending on traffic). Saves on gas, breakfast(buffet) and free aquarium tickets fo rmy wife and me are included. We'll just have to pay for the kids. The balcony will overlook Centennial Park. If we're high enough, we can see the fountain show with lights at night.
