We stayed the IC Le Grand in Paris on Dining Rewards free nights ( x 2 - my Membership + partner's Membership )
I am Plat AMB ( first night ), and partner is a newly minted Gold IHG member ( second night ).
They gave us the AMB upgrade for both nights - which was from 'basic' room, to top floor balcony King ( Delux ? ) with tower view from balcony ...
The Club upgrade was charged at 120 Euros for the first night ( didn't opt for the second night, as was planning to be out often ... )
For the 120 Euros, we were permitted to have breakfast on checkin morning ( we arrived off Eurostar train at about 09:00 hrs. ) - where French bubbly was available for self-service !!
Then, there was the afternoon tea spread, followed by 'twilight drinks' / canapes etc.
Given we only paid for the one day Club upgrade .... after breakfast the following day, you would think 'that was it' ....
We advised the Club staff, that were not checking out until 16:00 hrs. and that our Eurostar train was not leaving until 21:00 hrs.
We were offered the opportunity to return to the Club Lounge AFTER our day's sight-seeing for afternoon tea, AND come back to the Lounge after check out, to wait for our train departure time ( until we actually needed to leave for the Station ). Luggage kept downstairs ready to be collected later.
So, all up, we had great value from our Dining Rewards Memberships, and the one 120 Euro Club upgrade. Effectively, we got two days of Club Lounge upgrade for the price of one !!
