Yep, we are going to DC. Although funnily enough, the missus isn't really looking forward to it! We will be going there the day after our anniversary - I suggested we went there for our anniversary, but she would rather spend the day at SeaWorld instead, so we are doing Dine With Shamu for dinner (just booked it tonight).
SeaWorld was the first park we did on our honeymoon, so it holds a bit of a special place for us both, and we enjoyed that park more than any other in Florida.
