We are on a budget as well. I have concentrated our funds on the reception...great food with a nice variety, great desserts, beautiful venue,e tc.
Most of our guests are coming in from pout of town.
I cannot afford to invite all out of town guests to a rehearsal dinner(just the people directly involved will be 16-20 people), nor can I afford a next day brunch.
What have you all done as an alternative?
