hey guys,

i sent an email to the property with questions for my booking along with the upgrade policy,and got feedback there.

they said that the upgrade policy here is 1 level for platinum member and ambassador membership does not apply here.

They said that 2 level upgrade was probably due to unavailability at that time. Be that as it may, 1 level upgrade policy is also good, cause you can book a deluxe room and upgrade to club level. They also said that the upgrade is subject to availability.
