Just back from a week at SSR/Carousel...Carousel bus stop is second in the loop of five (Grandstand, Carousel, Paddock, Congress Park, Springs)...it's about a 5 to 7-minute slow stroll (the pace of walking when it's 90 degrees and humid outside!) to the Springs/main pool/Carriage House...about a 3-minute slow walk to the Paddock bus stop which is right behind the Paddock Pool (the new themed pool w/a water slide and bar/food), and about a 10-minute walk to Congress Park...as a PP noted, Grandstand has its own pool, too, which is not as big as High Rock (the main pool), but still a good sized pool w/a water play area for the little ones (and a food and bar service area, too) next to it...
I think this last stay at Carousel (my first time anywhere but Congress Park or Grandstand) convinced me that nothing is really all that far away, once you get the "lay of the resort" in your head (I admit to my first trip to the main area taking 20 minutes om the dark, because I kept making wrong turns and thus walking in circles)...
But the Springs is the closest to Carriage House/High Rock Pool/Artist's Palette--by about 2-5 minutes...
