Its about you and your fiance. We are having our wedding in the Dominican Republic without the presence of a Step-mother, set of grandparents, and my brother and his family. I gave them 15 months notice that this is what we were doing so they have amble time to save. Unfortunately they aren't coming and I understand. Its about us and what we want. We both sat down oneday and discussed if would still be happy if we were the only 2 people standing on the beach... We said "YES". Everyone else is a bonus to the day.
Relax and enjoy marrying your perfect guy at your perfect location. Best wishes!
