Is there a trolly that runs from the airport to sunset vista

No but there r shuttles there

There's a shuttle that would take you for $35.00 per person , also you could take bats taxi , but the shuttle would probably be your best if you don't mind riding with other people .

You can go to www.psta.com for schedules and routes of buses and trolleys running from St. Pete Clearwater International to the Gulf Beaches and The Sunset Vistas.

Not sure. We rented a car
