I used The Parking Spot, it's somewhat close and they had a shuttle that dropped you off at the airport. Covered. I think the shuttles ran every 10 minutes ish? It seemed less, took about about 10 minutes to get to the airport. Easy to find the shuttle it is yellow with black spots all over it. Very quick pick up as well, I called as soon as I landed and it was there by the time I got luggage and outside.
County Inn and Suites is also doing parking now.
I've not heard of Best Spot.
