No ideas on the benefits for Golds.
I actually stayed at this hotel last night, as usual I got an upgrade to a studio suite (in the Crown Room area); a bottle of red wine; flowers; small teddy bear; small box of chocolates and pen/letter opener set.
About fifteen minutes after checking in, I called Room Service for a bottle of Champagne (I can't drink it, but the person I was meeting drinks the stuff) and was very politely told "We would like to offer that with our compliments Mr Merry, would you like some chocolates as well?".
Not bad for GBP 120!
