Adding to the good reviews.
I just used GearFusion May 26-May 31 and highly recommend them. Todd, the owner, was wonderful. I had to postpone my trip twice due to illness and he let me carry my credit to reschedule both time, once the day before my arrival. He always responded to emails same day and sent new confirmations out.
Both drivers were friendly and safe and made the trip very easy. Cars were clean and well maintained. They texted the day before to confirm.
Got a text as soon as we got off the plane from Barb. There was a tiny confusion at baggage claim because she wasn't standing where I assumed she'd be with the other car companies, but we texted and found each other quickly. She played Disney music on the drive to Yacht Club and we had a nice conversation about Disney and Universal.
On the trip back, the driver, George, texted me about 40 minutes before pickup that he was running 15 minutes late and offered to send another driver, but since I scheduled with extra time (due to leaving on a Friday at rush hour) I was fine with the delay. And he was right on with his estimation, arriving at 5:15 instead of 5:00.. He kept apologizing for the delay even though we had plenty of time still. Turns out the family he'd picked up at the airport before me had a snafu with their luggage - the airline misplaced one of their bags. But it's nice to know that they have contingencies for that and were willing to get someone else there.
I would definitely use them again.
