Here are a couple things I witnessed at a recent wedding that you might want to consider including in your big day;
1. The groomsmen: As each groomsmen walked down the aisle and was greeted by the groom they each had their own unique greeting. One got a high-5, the other got a hug, and a couple had their own elaborate handshake routine. It was very amusing and it set a really fun tone for the upcoming ceremony. It also gave the groom and each individual groomsmen their own special moment in time.
2. First Dance: For the bride's and groom's first dance they performed a fully choreographed dance to "their song". They had obviously been practicing a lot and the final result was fantastic. I can imagine how much fun they must have had going to dance lessons for several weeks leading up to the wedding. Not only would it provide some much needed personal time for the busy couple, it gave everyone at the reception a wonderful dance to watch.
I hope those two simple suggestions get your imagination going and you find your own special ways to make your wedding exactly how you want it to be.
