We are getting married on August 18, and we are planning to leave the next morning or afternoon for our honeymoon. Since we are both teachers and have to be back for the start of the new school year on August 28, our honeymoon will be from Sunday, August 19 to Monday, August 27. We are not sure that we will have time for a gift opening in this time span because we want to be on our honeymoon as long as possible. We are thinking of just having close family members and any friends who could make it come to a gift opening and grill out on Labor Day weekend (September 1). We don't mind waiting a couple of weeks to open our gifts, but is there any sort of etiquette rule that says we should open gifts right after the wedding? Or if we wait, would it be better to just open them on our own rather than have a get-together?
