Hi there,

If I book a night with one of those free cat 1 -4 nights megabonus cert, will there be any problems for a pre-upgrade? So say I book a standard with the cert, and ask for an upgrade pre-checkin, will that mess up the certificate? Or should i be good to go? That's keeping in mind, that the hotel around checkin will be completely sold out, so I don't want there to have to be a problem with securing an upgraded room, without paying the high cost for it. I'm PLT btw.

Thanks in advance.
