Now that I have returned from my trip, I thought I would give an update on my first-ever rental car experience. I will post my experience here in hopes that anyone who happens to do so for the first time can learn from my experience.
As I mentioned earlier, I booked my car rental ahead of time. I heard some places required a copy of your car insurance statement so I brought it just in case. I rented for Enterprise and they didn't ask for it. Just my driver's license. But if you decide to rent a car, I would bring your insurance statement just in case. Booked it from MCO and returned it to Tampa Airport.
As for the toll road situation, I asked about the tollbox you can put in your car, and they said that if you drive through the tolls, the state of Florida will send you a bill a month later for the tolls you are to are to pay plus a $5 surcharge. They did direct me to another table to go to if I was interested in getting that toll box for the rental car, but I decided to eat the extra $5 if I had to deal with it. Turns out, in my drive from Orlando to Tampa, I didn't need to use any of the toll roads. While it probably would've been faster to use them, I saved some money as the toll roads were a non-issue for me.
But once you show them your driver's license, you they give you your documents for the car rental and they tell you where to go. Once you get there, an attendant will see your documents and tell you to pick any car in a certain section. You just pick your car and then go up to the exit booth. Now at the booth they asked me if I wanted to prepay for gas fill up. I decided then and there to do so but I don't think I would do that next time. They basically charge you as if you had nothing in the gas tank and you filled it up completely. Could've saved about $25 or $30 as I only used half a tank for the whole trip, but you live and you learn. Besides, I lucked out with that decision because they day before I returned my car rental, the state of emergency was declared for Hurricane Ian. Gas stations likely would've been jam-packed on my return day.
Finally, when I returned my rental car, I just drove to the lane at Tampa Airport that says rental car return. You park your car, leave your keys in there, the guy will scan the barcode on the car and give you the receipt for the rental. After that, you get your bags and leave. Pretty easy.
So yeah, that's my first-ever car rental experience. Hope anyone who may have their first car rental experience will find some value from this post. Thanks to all who gave helpful tips earlier!
