Hi, Richard!
What a wonderful way to celebrate your 20th wedding anniversary! Congratulations!
On your upcoming "second honeymoon," you'll be pleased to know that you can surely head over to Epcot, where Walt Disney World's professional photographers will be happy to take your photo with the stunning, iconic Spaceship Earth in the background...the real deal, not just a backdrop. :-)
Feel free to hand the photographer your camera, or have him or her take your pic with the professional camera. You can then get a
PhotoPass which will enable you to purchase or print your photo at your own convenience once you return home.
Have a wonderful trip! Be sure to send more questions as you think of them; I'd love to help you plan the perfect second honeymoon!
