One of the best parts about Disney World without kids was wandering where we wanted to wander, whenever we wanted, and taking as long as we wanted to get photos.
And since I have very little interest in rides, the lines were minimal!
It really helped that Doug has now started experimenting with the D5000 while I tote around my D300s. You wouldn't believe how long he wanted to hang out in the bird areas of Animal Kingdom! (I think I've created a monster!)
