Here's a tip: If you are getting married at the beach, chances are it will be windy, this makes a candle lighting ritual almost impossible, it will also make you, the bride, look like you have just taken a jog through the forest, try choose a hairstyle that will still look great "windswept". Some celebrants may shy away from beach weddings because they can be problematic, I say there's no problem that can't be creatively solved.
