Currently booked at OKW Nov 27 -Dec 2. Really want to switch to BCV at 7 months but I am very concerned about cancelling the original then having the BCV gone before the cm can book it, especially since in order to cancel and free up the OKW points I would have to wait until 9 and call. Has anyone ever lost both reservations in the process and ended up with nothing? Are there any ways to avoid this pitfall ? Very concerned.
