This was our fourth rental experience with Sixt, and the first time to pick-up in Tampa. We reserved a 4-Runner/Grand Cherokee class SUV around four weeks in advance, and the day before we arrived we discovered a fifth family member would be traveling from the airport with us. After a quick call to customer service, we upgraded to a Tahoe / Yukon / Sequoia class SUV for a very reasonable rate increase. We had a great experience at the counter with Ms. Abrienne, who was able to get my brother-in-law added as a driver with no trouble whatsoever. A quick escalator ride took us to the correct level of the parking deck, where we were given the keys to a Tahoe with less than 5,000 miles and all of the bells and whistles. The vehicle was great - we enjoyed the sunroof, and loved Apple Car Play. It was very nice knowing we had the extra row of seats when we needed to carry 6 or 7 people, and had TONS of luggage space when it was just 4 or 5 of us. We have always had very nice vehicles, friendly staff members, and 5-star service with each Sixt experience. Looking forward to traveling with Sixt again soon!
