My daughter and I took a taxi to and from the Poly to the Citywalk complex. We left at 7:50am on a Thursday, no traffic on the way there. It took about 15 minutes, and it cost $45. We left around 2:30, once again, no traffic, and it took about 15 minutes and cost $43.
I think the best deal is to go through
Dreams Unlimited and get your park passes with free Mears transfers, that cab ride was a killer.
