Here is my daughter in line, and in her own little world.
Other tips:
When an attendant comes around to check your seat belt, don't hesitate to ask them to take a picture of you on the ride. I've never had one tell me no.
Carry your camera and extra batteries, film, memory card in a small case right on your person. Make sure it's hands free.
If you want to plan ahead, have your family wear colors that will go together and not clash. This makes it easier to scrapbook later and you all look like you belong together. One year, we wore red white and blue. This made for fun pages and amusement parks are the epitome of summertime, as are the patriotic colors!
On the other hand, I like to wear bright colors on my daughter so that she is easy to spot when she is climbing up tall nets and running across bridges and the like. These make for fun pictures, too. (especially with cotton candy in the shot!)
Scrapbooking amusement park pictures can be a challenge, since it can be hard to find stickers that match your theme. You will probably have to think outside of the box. I know for a fact that Creative Memories doesn't make amusement park stickers any more. Try to match your clothes, and remember that stars always work with amusement park pics.
Scrap Happy!
