Very expensive and make trouble to get spg points
We booked with Amex travelservice.
They refuse to ad spg points to my account although i payed with my amex card.
the explanation they give is that a third party (amex travel service) payed in my place!
Whatever!!! 
If this is such a problem to attribute points for a 4 digit number bill beginning with 2...well i'll stay at another hotel next time...mariott, sofitel...they don't make a fuss with their fidelity program!!!
it's a way of binding customers to your brand....well bad luck spg!!! never again!!!
Thank the parker meridien!!!!!
