Hi again. Found something I was looking for. At PPH the other day we asked the lady behind the counter (not the checkin area, but the other counter) for a flat fee voucher. She handed one over, which we then misplaced, so we got another later. I'm looking at the one we misplaced.
It's a blue voucher from "Yellow Cab Co" and it's a "guaranteed fare taxicab coupon". I don't know if you can get it at every area resort, but it seems like it.
The flat fee for LBG is $40 via Ball Road or $50 by freeway. So ask at your resort for that. The voucher says that the meter will run, but "flat rate is still honored".
