My fiance and I are having the ceremony at the same location as our reception. Would it be awkward if we did the receiving line as everyone entered the reception ballroom approximately 20-30 minutes after the ceremony ended? We're getting married in an old theatre that has a lot of cool stuff to look at in between so I figured 20-30 min to mingle in the lobby and look around wouldn't be too big of a deal. This would give us a chance to do our 20 min with the photographer direclty after the ceremony and then be upstairs to greet everyone. Would this be weird? We have approximately 230 guests that will be attending.
