We don't know as they all verbally say "Oh yeah we are going" when we have seen them at get togethers (which is akward....HELLO we didn't even invite you and your talking about coming down during our wedding!). Whether they go or not is up to them we just are going to make it very clear what functions are for who we invited to the wedding (Goingto the spa beforehand, getting ready, "Welcome/Rehearsal" dinner, wedding ceremony, breakfast the morning after, etc.). Where do you draw the line though? Our wedding is on the beach and you can see the area from the pool so what do we say...oh by the way please don't sit by the pool this afternoon so you can't watch our wedding? But I feel like some may do this and it seems like it would feel like getting married on a public beach where whoever wants to can witness your wedding.
