If POFQ is an official host resort, the event organizers may be providing shutttle bus service.
If not, best bet is a taxi, which would probably be around $10-$15 one way, and less than 10 minutes.
Unfortunately, Disney bus transportation to EWWS is very limited, and getting there from POFQ would require 2 transfers. First take a bus to either DHS or Epcot (whichever comes first.) From the park, take a bus to Pop Century. At Pop Century, a bus runs to EWWS every half hour (about 5 minutes past) when events are scheduled. With wait times for the first 2 buses up to 20 minutes, and up to 30 minutes for the third, all this could easily take 90 minutes.
