I just called the Platinum reservation line to make a reservation. I was told both hotels in the city I was going to was sold out. I inquired about the 48 hour Platinum Elite Guarantee. I was told by the representative that the hotels likely requested for special permission to block the guarantee. What is the point of offering a benefit of membership when you are not going to always honor it? Why should I stay loyal to a chain that changes the rules to their benefit? Has anyone else experienced this?
