A great option for your wedding is to rent a vacation beach house. It allows for the family to be able to all stay together and most vacation rentals on the ocean usually have a great spot of beach or a public one really close by. As well most higher end homes have great landscaping for shots with beautiful flowers and greenery.
This couple did a first look before the wedding and then had the ceremony right in front of the vacation rental.
The infinity pool offered some great options for photos as well.
