Every year we do a girls weekend and go to this all day wine expo. Last year I was DD since I had just found out I was pregnant, but this year I'm trying to figure out how to manage pumping while attending.

The expo is from 11-6 and we usually are there about the whole time. Initially I had thought I could go to my car and pump halfway through. It's in a large convention center though, so we'll be parking kind of far away so I think if I have to leave to pump in the car I'll be gone for about an hour.

Another thought is to buy a manual pump and pump & dump in the bathroom? Has anyone done that before? How long does manual pumping usually take?

Any other suggestions? I doubt I'll be drinking a ton (as I have in the past) because I can't imagine a hangover with a baby right now (LO will be 4.5 months when we go).
TIA!
