When shooting photos on vacation, in addition to the traditional shots of the family in front of famous landmarks, and those landscape shots you swear you're going to frame, but never get around to it, but try taking a few alternative angle shots too. Its fun!
What do I mean? Well, try an other vantage point, like looking straight down a curving stairwell, or up at a beautiful cornice, like this shot shot I took in Annapolis, Maryland. You just might find they become some of your favorite snapshots.
