Open Ended Trip Reservations?
We're going to take the train to Denver in October and visit our daughter.
I'm not sure if we'll be bored, and want to come back in a week, or enjoying hanging out in Denver and want to stay longer. It's pretty likely that a week will be plenty, but I like to keep my options open.
From experimenting, return airfare would be only $90 more (for the two of us), if we didn't book a return flight until we'd been there a few days. That is, when I search for flights for the very next day, it's only $90 more.
Any thoughts on the best way to do this?
