Quite all right -- it was a fun party, and the food was both tasty and plentiful. (Not that I'm ever going to object to more baked goods from you.)

As for chairs: I don't really think you could put more in there. Given line-of-sight issues, having some folks sitting on the floor was probably necessary. You might want to invest in one or two more large squishy pillows for the folks on the floor, but that's really the only thing I'd change...
