We have been on a WL alone loop, WL/CR loop, the WL/GF loop, a WL/Poly/GF loop, and last but not least, a WL/FW loop. I guess it all depends on the time of the year and crowd levels.
We only waited once for the bus to DHS on the WL/FW loop longer than the advertised 20 minutes. But the WL to MK bus runs about every 10-15 minutes it seems. Much quicker than the boat.
