I have been Platinum for several years and finally tried to take advantage of the guarenteed reservations perk, but all three times was told sorry, it is up to each individual hotel to decide if they honor this perk. All three said sorry about your luck. One of them the stay is even 9 months out. I'm not looking for rewards availability, this is for a paid stay in Dublin at the end of August. So I ask, what is the point and how can you market this as a perk if it isn't honored?
