My favourite hotel with them with value/price with member rate was this Ritz Carlton in Portugal (less than 200 USD/night for standard room):

If you use their site, they give you some money that you can use to eat at their pricey, but amazing restaurants (also 2 of the hotel's restaurants has Michelin star, but I haven't tried those yet).

Their swimming pool / jacuzzi is bad, but the nature, the castle and the room is great.
