Since you're exchanging vows in a tropical location, bad weather is a possibility. Along with planning for an alternative location for the ceremony, you should also have some indoor options available for guests staying at the hotel. Especially at destination weddings, friends and family are normally at the resort for at least two or three days. If it rains all day when you had volleyball, water sports and picnics on the beach for all your guests, you need to have another idea in place. Check with the location ahead of time and find out what indoor activities are close by. Make up a list to give to everyone when they arrive so they aren't stuck inside a tiny room. Movie theaters, malls, family fun centers, clubs and other entertainment might be closer than you think.
