Buses run every 20-30 minutes. They are not on a set schedule just a constant cycle, so you should not have to much of a problem with them. If you want to be near the main pool you want to request near the Hospitality House. The bldgs are 11, 12 (smoking), 13 and 14 directly across the street...62, and 63 (to the side) and 23, 24, 25, 26 behind. The bus stop for 11-14 and 62/63 is at the Hospitality House and is the last pick up point before the buses head out to the parks (which in turn makes it the last stop when returning). The bus stop for 23-26 is right in front of the loop and is the first pick and first drop off stop for the buses.
