We booked only a week or so before our stay as we were waiting for American Express points to transfer to Club Carlson points. We used 100,000 points for 2 free nights stay in a studio. This was a great deal as it was. We then paid for an extra night. No upgrades were available to pay for at the time of booking which was understandable at short notice but disappointing because it was my 40th. However my husband signed up for any upgrades that would become available which they did the day before our arrival. He paid to upgrade to a 1 bed suite and then on arrival we were upgraded to the most fabulous 2 bed suite with a huge balcony. It had a lovely view of Big Ben and the 2 bedrooms had river views too. Spectacular! Balloons and a card were delivered from housekeeping and some beautifully presented nibbles from Guest Relations. What a lovely touch. The suite was amazing. The best night's sleep I've ever had in London and wonderful to have the kitchen and so much space. Can't stop telling everyone. Thank you so much Plaza on the River.
(For those paying top price I don't think they would be impressed with the tatty robes, the noisy bathroom pipes or the music from the ballroom though it didn't go on late. If you need an acoustic consultant let us know as my husband would be happy to help). That aside, it's still a Wow!
