We have our venue for the reception, which I booked before forming a guest list in hopes that a small venue would reign in my mother's need to invite everyone (it didn't). Needless to say, we're a bit over capacity, but with an out-of-town wedding for 90% of the guests, I'm feeling pretty confident of a >10% decline rate. There was a thread steering brides toward only inviting the number of guests that you can afford and the venue can fit, but we all have sins... a second cousin that's a courtesy invite, the roommate from college that's too busy with grad school; they need to be invited, even if they put you over (especially when mom is inviting more of her friends than the bride's!).
So, how many people did you REALLY invite? And, do you include yourself/WP in the headcount (weird question; my venue said the room capacity is 70, but the seating layout showed 7 rounds of ten plus a table for the wedding party B&G. Anyone else see that?)?
