I have a reservation for 6/4/19 that I want to cancel, that I made with a free night certificate that expired 4/9/19. But they won't let me move it to a different reservation that I do want to keep. I tried email, phone and chat. I guess they really have cracked down and there's no way around this. I will still be in Prague, just at the Hilton instead of the Intercontinental. So I guess at this point I might as well keep it and go check the room out. Who knows, maybe my husband and I will be fighting that night :-)
