it rained when we had our bridal portraits at MK. It was not fun. It was actually the worst day that we had there. EVER. However, the cloudy sky (it had stopped raining long enough to get good pictures) made some of the shots look really cool. So, embrace the crappy weather; you did pay for it after all. And we got married in January, so not only was it rainy, it was really cold too. Good luck!
