So the four of us were supposed to fly SEA-TPA in 6 days, and my husband has had to bail on us because of work. I'm going to be on my own, traveling with my 4-year-old and our 8-week-old. This will be the 8-week-old's first flight, and my first time traveling alone with two kids. I'm not at all worried about the time spent on the plane, but everything before and after

I'm trying to figure out which stroller I should take. We have a Sit-N-Stand, which carries the infant bucket in the front and allows 4yo to sit or stand in the back part if she gets tired. We also have a (single) Chicco Cortina travel system, which I would mainly use for carrying the infant bucket, but which could carry my 4yo (without the bucket, of course) in a pinch while I carried the baby in an Ergo.

Other details:
-- We'll probably be doing a lot of walking in TPA
-- I will be taking car seats for both kids, as we'll have to take a taxi from the airport to our hotel
-- Baby has her own seat on the outbound flight, so we'll need the infant bucket on the plane (I don't want to check either car seat as luggage anyway)
-- We have a connection in ORD on the outbound (AA) and in IAH on the return (UA)
