I got a good rental car rate from budget for a one way rental from MCO to RSW.

Budget (to their credit really) had a notice posted on my rental confirmation that the florida turn pike no longer accepted cash tolls, and that if I were to drive on this road I'd have to use their sunpass system. There was some language that also suggested that I could bring my own sunpass. Historically I have just paid the cash tolls. If I use their sunpass system, I will be charged $2.50 a day plus tolls, which DON'T have a reduced rate (which i find obnoxious).

I may be able to avoid the turnpike as I am just going from MCO to fort myers, but I am considering buying a sunpass transponder as I go to Florida once a year and it appears that eventually a lot of highways will be cashless. My understanding is that it is fairly easy to update your profile online so that you can use the sunpass with a rental car.

Does anyone have experience bringing their own sunpass transponder and opting out of e-toll? I would assume they would let you do this but can't find anything in their legalize to confirm this. I don't want to show up and have them tell me I need to use e-toll.
