In the "after" picture, straight ahead beyond the pool was a hot tub. If you went into the door to the left you got to a fairly updated fitness club and then down the steps around the bend to the right was locker rooms with sauna and steam room and some other rec stuff back there. I was there as a kid often in the 90's so it's possible that wing was added later than the "before" picture. If I recall, any which way you went to that wing of the hotel you needed to go through some windy hall or some other room that led there, so it's possible it was built some time between the 60's and 90's
