They have taxis and local shuttles around the beach area.
Yes there is beach shuttles, taxis and Uber.
Siesta Key has a free trolley up and down the island 10am to 10pm 7 days a week, with service to midnight Fri and Sat....and obviously Uber is readily available as well in the area.
The shuttles are great and there is no charge to ride. They do depend on tips though.
There is plenty of transportation
