Tolls from Miami to Orlando via FL Turnpike

[courtneymarieclare]

Hi all! DH and I live in Miami are thinking of taking a spur of the moment trip to WDW this weekend. We'll be taking the Turnpike and according to the toll calculator we should pay (with Sunpass) about $15 in tolls both there and back. However, when we moved here a few months ago and drove down I could swear we paid a toll somewhere between Orlando and Miami that was a whopping $25. I remember going through a toll booth where we didn't pay a toll, but they gave us a little ticket. Miles and miles and miles later, we went through another booth where we gave the ticket and we paid the toll, which again, I could swear was $25. Maybe I'm insane or just not remembering correctly, but I just want to make sure before we definitely decide if we're going or not.

So, to get to the point, can anyone who has driven the Turnpike between Miami and Orlando confirm around $15 for tolls with Sunpass?
