The ceremony begins at 2pm and will be a full Catholic Mass - probably around an hour or an hour and 15 minutes. The distance between the ceremony site and reception site is a good 20 minutes, plus time to park down the block, walk, etc so I feel like starting the cocktail hour at 4pm would force people to rush. (Also, half of the guest list is from out of town so they will have no idea where they are going and might need to check into hotels at this time) Would starting at 5pm be too much of a gap? Should it start at 4:30?
