Concur:
Flight to SVG cancelled so I'll only need 1 night in the hotel, not 2.
Go to Concur. Options are 'cancel' and er, that's it.
Try adding hotel to itinerary (with the idea that if it works I press cancel on the old reservation, you can tell how much faith I have....)
Computer says 'no, that didn't work for unspecified reasons'.
Try calling the hotel. They won't deal with me cos it was booked through an agent.
Find CWT travel agent number, ignore dire warning about cost for out of hours service. Operator can't find my hotel reservation on the system, even though Concur gave me a reservation number.
Eventually they phone the hotel and the reservation is found and changed. 18 mins on the phone later.
While if I'd booked it straight on the Scandic website I could have change it online in minutes, like my colleague (who is high up enough that he laughs in the face of travel policy and books everything direct himself) did while I was standing the queue to get my flight changed.
