The two pools are probably the equivalent of two stories apart. The curved pool is on level -3, reception being on floor 0 about level with the parked cars. We're the equivalent of four stories above reception.
Of course if you live in a typical UK house, you probably have around 13 steps between floors (we have 16 in our Victorian house), so going from the balcony to the pool would be like going downstairs 14 times and more importantly, going back up would be like going upstairs 14 times!
Needless to say we rarely went back for anything other than a rest.
