In one word, YES! From the moment you arrive, you will need to be directed to the parking area, so you will need a sign for that. You also want to make sure you are at the correct venue so make sure there is a large Welcome sign announcing the wedding and who the bride and groom are. There are usually signs for ceremony seating within the venue as well as name tags for seating at the reception. A good wedding includes signs around the venue with photos of the wedding couple and fun facts about each of them. Childhood photos of the couple are always a big hit at a wedding.
