Upgrade: Booked Executive Room with Club access, upgraded to beautifully renovated One Bedroom Suite on a 3 for 2 stay. I think we were the first guests to stay in the renovated room and it was spectacular (on 4th floor).
Early check-in: Arrived 2:30pm, room was ready.
Breakfast credit: Daily breakfast, including buffet, in the Palm Court for two. I ordered a side of beans with the buffet one morning, and there was no charge for it.
Amenity: £85 property credit, used on F&B and for laundry service.
Late checkout: Offered at check-in, took it and left at 3:50pm on checkout.

Renovations are gorgeous and the club lounge is rather nice, never over-crowded and with good food offerings and great service. One of the champagnes on offer was Perrier Jouet, though I valued the unlimited lattes and cappuccinos more! ^
