we like to get those official pictures that they take as you enter the park too. These tend to be the few shots we have as an entire family, so we take a moment to move the stroller out of the shot, take off our bum bags, and water bottles and just make ourselves look presentable.
(Nothing fancy, but the first one we went to look at we looked so silly with all out 'gear' in it, that we didn't buy it even though we all had nice smiles).
