My family is renting a mini van in Texas and driving to Disney. We'll be coming down I-75 and getting on the Florida turnpike to I-4. I just wanted to double check that we can still pay cash at the toll booths while on the turnpike. I really don't want to purchase a transponder but if I have to I will. Also I went to the sunpass website and it's saying the total cost for the tolls will be 3.76 (one way of course). That sounds really low for tolls.
