We stayed at Pop in October. We also had reservations for Boma's, ours were for breakfast brunch.
We took a taxi. It cost us $25, including tip.
We had asked around when we were - if we had taken the busses from Pop to park to AKL it would have taken about an hour - give or take, depending on crowds, etc. The taxi seemed to be the best solution. We called the front desk, they called the cab, and it was waiting for us when we got to the front.
