I have a question regarding the Hyatt suite upgrade certificates good on paid stays. I am planning to make a paid stay in Japan. In Japan, it appears that they charge per person rather than per room. Since I plan on upgrading to a suite anyway, can I make a reservation based on the lower single (one person) room price even if I am staying with my wife? Or do I need to reserve and pay for the higher double (two persons) price? Thank you.
