Trying to find what I had as to the original price. Some I only have some things on notes but they were all at least 35% more than what I paid. You get 20% off the price that you find that is lower than their cheapest price. Now you have to book and get a before and after price. Before you just got what the cheaper rate was and then what the discounted rate is. You still get full benefits, credits and points on SPG stays, including upgrades. As a Platinum I get continental Breakfast for 2 + club room if any (amongst others)
Grosvenor house Dubai, Prepaid (no breakfast) 1100AED our rate 694AED with breakfast (used SNA to get suite, included breakfast and had club lounge)
W Times Square, Prepaid USD$800+ mine USD$481.51 (Platinum continental breakfast) (upgraded to suite)
St Regis Rome, Prepaid Euro650-700 our rate 315.11 Euro (Full Buffet Breakfast for 6 - one room upgraded)
Prince De Galles Rome Euro 1055 our rate 567 Euro + 1000 starpoints (SPG50 discount - was Paris fashion week so completely booked out) One room upgraded to 2500Euro Suite while all these fashionista's complained. We had paparazzi outside the hotel regularly. Full Buffet Breakfast for 6.
Sheraton Mirage Gold Coast $450prepaid ours $220 (nothing as was gold then)
Others I can't find are Westin Dawn Beach, Sheraton Hong Kong
Had a couple of others but cancelled (because they are flexible) when better deals came up. Unfortunately I decided to do some cleaning up and do you think I can find the emails. One was Sheraton Times Square for New Years. Was about $1100 for New Years and got down to about $500 but cancelled and went to Westin Times Square when their rooms changed to $300 (lasted a few hours). St Regis New York (was about $400 cheaper - changed to Westin), Sheraton Hong Kong, The Chatwal New York (was over $700 per suite discount on SPG50 over Christmas - changed to Westin).
