I plan to drive from Miami airport to Orlando, and then stay in Orlando for 1 week. I heard that express toll is about $10-$12 for unlimited toll road usage. Is it worth it?

I do not think it's like that, because I've traveled several times that route and the toll charge is around 20 dollars

Well, if you walk a lot in Orlando, there are a lot of highways there. But if you are just on the way to town and parks, I recommend using the I95 to Cocoa Beach which spends less toll. a Sun Pass costs $ 25.00 and can be charged from $ 15.00. its use is undefined and $ 40.00 is less than $ 84.00.
