We use the baby centers liberally ever since we had a kid. Took baby at 3 months and at 7 months old, returning again at 15 months old, baby still nursing.
My wife struggled to breastfeed for the first few months so really was strict about pumping to keep her supply up. We stuffed ziploc bags with ice to keep the milk chilled, in a cooler.
It's also a great place to refill water bottles, take a breather if it's hot, and there are a ton of other kids for older kids to play with while mother either feeds baby or pumps.
