Hi! We just got terrific airfare with SW and are flying out of MHT. We have to schlep two 2-year-olds plus strollers, Nana and carryons. Is there anything quirky about MHT's SW terminal we should be aware of? For instance, can it be chaotic? Are the security checkpoints narrow and tight-fitting? (I had a horrible experience trying to get the kids through security at the AirTran terminal at Logan. It was a very tight fit.) Are there play areas like some airlines have? Concessions? Thank you!
