If it's before 4, I recommend taking the bus to AKL as it's really close and switch there for springs. Any other park I would usually go to saratoga springs and switch buses at Congress Park bus stop (and if I'm heading to the east side of springs or plan to see all of springs, I just walk to springs from there as you start on the edge of springs where the old bus stop used to be.).
Keep in mind that buses don't go back and forth like a city bus does so you might get off the bus to springs when you transfer and you want to ask the driver or pay attention when it's time to get off.
