For our first dance, Carissa and I decided to use the final iconic scene from the film Dirty Dancing. To learn the whole dance we needed to re-watch the video over and over. We had taken some beginner salsa lessons before as well so that helped with some of the moves. However, even though we had known a year in advance, we didn't seriously start practicing until a few weeks before the wedding. We had to cram like crazy and with all the craziness of our wedding day it's a wonder that we remembered anything at all.
In the end, we didn't get it perfect, unfortunately, but as they say in horse shoes and hand grenades--close enough.
