If you're flying in and renting a car at MCO, look into the Visitor Toll Pass. Most of the roads/quickest routes to and from MCO are toll roads. We use it every trip, and it only takes about an extra 5min to walk over to A terminal to grab it and then get back over to B side (our flights and therefore luggage are usually in B terminal.) DH grabs our bags while I'm getting the toll pass and then meets me at the rental car counter. And then you just drop the toll pass in what looks like a mailbox when you go back to MCO to fly home.
For anyone who hasn't used VTP:
You need to download the app, and make a "reservation" for when you will pick it up. The hang tags are in what looks like a big vending machine in A terminal, on the same floor as the rental car desks. Sometimes there is an employee there if you need assistance. You should pick a time that you will pick your tag up BEFORE. So as an example, our flight lands at 6:44, and I have a 7:30 pick-up in the app, and if we get delayed, I can edit the pickup time. Apparently if you are "late" for your pickup time, you have to make a whole new "reservation." Once you get to the machine, you scan the QR code, and it drops a hang tag for the mirror of your rental car. You link the license plate to your hang-tag in the app before exiting the garage (plate number and state.)
They charge a $10 deposit to start, and then deduct your actual tolls from that $10, and any tolls past that $10. If you don't return the hang-tag, there's a $10 no-return fee. You're able to just drive directly through all of the sunpass toll locations and it's great and cheaper than what the rental car companies try to charge you. Sometimes it takes about a month for them to refund any difference between the tolls and the deposit, but in the end, you only pay for the tolls and nothing extra.
