I chose Royalty among a number of different exotic rental companies in Las Vegas, largely based on reviews here and elsewhere. I was not disappointed. I had originally booked a McLaren 570s, but was informed the day before that it was unfortunately in the shop due to maintenance and would I like to chose another car. I was given a number of equal or better options, and settled on a convertible Ferrari 458 Italia.
The entire process, from the initial reservation through to pick up and drop off was easy and pleasant. More importantly, the car was in excellent shape both inside and out, and was clearly well maintained. It performed flawlessly through my 12 hour "test drive". I would not hesitate to recommend Royalty to anyone interested in trying out an exotic, and will likely use them again in the future.
