The photographers who are in and around the parks to take photos now will give you a little plastic card when they take your photo. As you get more photos taken in different locations you can just give them that original card, and they will "add" the new photos to that. If you don't have the original card, they can just give you another one for those particular shots. When you get home, you just go to the website listed on the card and type in your card number, and all the photos will be there. We did it in early December and it worked out well. Then you can order your photos from home. No more waiting in the lines at the end of the day at the parks and making too fast decisions with tired ones in tow.
