I originally planned to travel in coach on Amtrak's Lake Shore Limited for my 15-hour trip from Cleveland, Ohio, to Pittsfield, Massachusetts.I've enjoyed traveling in this section of the train during past trips. Coach tickets are budget-friendly, the baggage allowance is generous, the seats are comfortable, and the café sells snacks and soda.However, on this trip, I decided to try to upgrade my ticket with a bid — and it worked.Here's what getting the upgrade and taking the ride was like.

Amtrak passengers can bid to upgrade their tickets, and my $110 offer scored me a roomette.

Amtrak uses a process called BidUp to give riders access to certain upgrades.
