Cost and destination of wedding abroad?

My Daughter is thinking of getting married abroad next year. She hasn't settled on a destination, just somewhere hot. It will just be her and her fiancee. My Husband and I want to pay for the whole thing but have found the pricing in the brochures to be quite confusing. If anybody could tell me where their own wedding abroad was and an idea of the cost then it would really give us a helping hand .... and give us an idea of hard we will have to save : )
