We took a cab from POFQ to Orlando Premium Outlets on Vineland. The one-way fare was about $20.00. It was at a non-peak traffic time (about 10:00 a.m.).
Later that day, we took another cab from the Buena Vista Factory Outlets on SR535 to Downtown Disney (at about 3:30 pm.). The fare was about $15.00.
Cabs readily available at front of hotel. It worked well.
