... It may sound silly, but one thing I'm excited about is being able to wait in line for rides without having to entertain kids!
Not silly at all! Totally get it -- that is precious time you get to spend together!

That will be a race weekend at DLR, so being organized and prepared will help you both to get the most out of your weekend away.
If you do the WOC Dessert Party, let the CMs know at check in that you are celebrating a milestone anniversary. If there is a place to note it on your reservation, put it there, too.
For more budget friendly ideas, here are some things that DH and I love doing in the parks:
Sharing a hot fudge sundae at Ghirardelli in DCA
Sharing a popcorn while sitting on a bench and people watching
Watching all the live music in the parks and in DTD
If you dance at the Royal Swing Ball, let the band leader know it's your anniversary. He'll dedicate a song to you. In fact, most, if not all, of the bands and musicians will do something like that for you throughout the parks.
Make sure to get your "I'm Celebrating _______!" buttons and wear them proudly all weekend.
