Our ceremony and recption are in the same location so the plan is for FI and I to do a first look and get as many photos done as possible beforehand. We will probably still use the first 20-30 minutes of cocktail hour to take more photos at the venue, but if we arrive at our cocktail hour midway through and mingle, can we cut down on the amount of time we are doing table vists? FI's parents have a very large guest list, and FI and I do not personally know a large chunk of them, as they are his parents' friends and distant relatives he has never met. We both would rather be able to spend time with the guests we actually know at the wedding, so if we spend cocktail hour meeting and mingling with the guests we do not know, would it be rude or innapropriate to only stop by these tables later on for a very quick hello and thank you for coming. Since there is no lag time between when the ceremony ends and reception starts we also do not want to do a receiving line (there are probably going to be about 200 guests), we'd rather be able to make cocktail hour and enjoy some of the food that's being served!
