I'd like to share a wonderful experience I just had with the Plat line. I am attending a conference later this week, and booked in the room block. I went online to look at current rates and found the prepaid rate was $25 less than the conference rate. AND, the conference rate was only good for the first two days of my stay, the 3rd and 4th night would be $20 and $40 more, respectively. So the conference rate would end up costing me approximately $160 MORE. Hmmph! I noticed that the cancel window for my conference rate passed on Monday (eek!) and that my one-night deposit would not be refunded after then. Soooo, I called to see if there was a way to keep only the first night of the conference (with the deposit applied) and change the remaining three nights to the prepaid rate. The Plat concierge was AMAZING! She was able to accomodate my request, and do me one better. Instead of the additional three nights at the prepaid rate, she found a separate prepaid rate that gave a third night free. It was $20 more for the first two nights, but the third night was $0. Sooooo, after calling and having her redo my reservation, I am saving over $200 on this stay! Thanks, SPG, for a great experience with the plat concierge!
