We had our heart set on a saturday night receptionfor 125 in May 2012 but the venue we fell in love with offered us really great discounted rate if we choose to get married on Sept 2 which is the sunday before labor day. Technically most guests will probably not have to work the next day but Im not sure about a Sunday. We also found another location that is 25 dollar less per person that's not as nice but that can accomodate a saturday May 2012 date.
Just a few other things to consider:
Venue #2 - we would need to bring in top shelf liquor and pay $8 per chair extra to change the chairs ( they hv really old ones that we can pay to change to better ones)
Is the 25 per person savings worth a Saturday reception day?
