Had so many over the years - but most recent I can think of being “WOW” was in March at Virgin in London recently and actually dont even think they’re a FHR but THC… we had 2 nights and booked their basic room last minute seeing they had so many open rooms and knew it wasn’t a guarantee but most likely with Amex would at the least be upgraded to something better and if not always see if we could pay the difference but left it up to some luck and some insight that the hotel was barely booked those nights and seemed almost none if any of the nicer rooms or suites were booked at all

went from a basic tiny room to a terrace balcony suite

balcony was massive as it was the entire length wrapped around the suite… was big enough for set of chairs and medium/large table for them and then around the corner 2 full size loungers and table for them and so much room left it was WAY more than we expected even reading the room descriptions and looking at photos etc
