I've been searching around for Park Hyatt Tokyo rates. I really want to experience it at least once in my life but don't want to spend $428 / night (52K yen) without taxes for it. There used to be 50% off United Airlines certificates for Rack Rates. Does anyone out there know of any similar type certificates still available since UA's certs are now discontinued? Otherwise, does anyone know of any other means to secure a more inexpensive rate? Thanks.
