Taxi from POR to Poly..how much?

[Coloradomom]

Next Sunday we are planning on attending 8AM Catholic Mass at the Polynesian. I know we could take the bus from POR to MK and then catch the monorail to Poly,but Iam not sure I will be able to get my sleepy family going in enough time for that.(It will be our first full day there). I thought about taking a cab from POR to the Polynesian. Does anyone have an idea of what the cost for that would be? Also to allow enough time what time would I want the cab to pick us up? Thanks for your help!
