First, you need to decide if a beach wedding is really feasible. If you have elderly and disabled guests, how will they get to the ceremony? It's hard enough for perfectly able people to walk on sand -- let alone an elderly person.
What time if year or day do you want the wedding? Of course, you don't want to have a beach wedding in the winter, but having a beach wedding ceremony in the summer on a blazing hot afternoon wouldn't be too great either.
You will need to rent special items like a platform so chairs won't sink into the sand an a canopy to protect guests from the sun. One of the best ways to deal with this issues is to contact a company that specializes in renting equipment for beach weddings and knows all of the permit requirements.
Another thing to think about is how to dress for a beach wedding. For one, forget high heels that will trap you in the sand. You can buy beach wedding sandals.
Proper beach wedding attire does not include an elaborate wedding dress with a huge train and a heavy black tux for the groom. Beach weddings call for light and casual, but elegant attire, like a simple flowing silk or cotton wedding dress. Remember that natural fabrics are more comfortable than synthetics. Why should you worry about comfort? You don't want to be sweating profusely and ruin your hair and make up.
If you are having a beach wedding, don't ask for guests to wear black tie attire either.
