Carol,
I recently booked on line a 15 day stay at Park N Fly the Parking Spot in April for a trip to the DR. I joined the Spot Club and got a AAA discount and it cost me $197 that includes $28 in taxes and tees. The actual parking cost is $11,27 per day plus fees and taxes. That is for parking outside and paying ahead of time. I used Park n Fly before they were bought out.
Try joining the club, use AAA, and go through the process to see your final cost.
