PlatePass® All-Inclusive Tolling must be sold for the length of the rental contract. It cannot be purchased only on certain days. PlatePass® All-Inclusive Tolling is a duration-based model and provides unlimited toll road access for a low daily fee per the length of the rental agreement.
  
Customer must either OPT-IN or DECLINE at time of reservation or at the rental counter. All daily charges are included on their receipt when they return the car. No billing is done after the fact unless they fail to select the tolling option and still uses SunPass. EPASS or LeeWay ONLY Lanes.

If not enrolled at time of reservation or at the rental counter, and user incurred toll charges by utilizing a dedicated or express lane, a $15.00 administrative fee + toll is assessed for each infraction to a maximum fee of $105.00. These fees and tolls are charged separately after the completion of the rental.

$10.95 a day for all of your tolls sounds pretty good until I tried to figure out how far I would have to drive to make this plan worthwhile.  I didn't check to see if this plan covers bridge tolls, if it does I would use it to go visit Sanibel Island, a $6 toll.  Of course once on the island I'd remember that I needed something at Publix, over the bridge I go. Once I got back to Sanibel I would get a hankerin' for an Egg McMuffin at 2 in the afternoon, hello mainland. Going to one of the beautiful Sanibel beaches, better go get that bikini wax I've been wanting... you get the idea. You're better off with a Tolltraxx transponder. A one time $7.50 service fee ($3 of which is refundable) and a $.50 fee per toll. Use it a lot, use it a little, don't use it at all. No daily fees, ever.
