I used to find an inexpensive limo for my daughters prom. Royal Oaks Limo were both reasonable and very professional. We ended up buying two hours with the driver and new, beautiful Lincoln MKS. I paid $ 168 for three hours with gratuity, but chose to tip a further $ 20 because they were so good. The driver called me after he had done the final drop off to let me know that the prom goers were at the school and all was well.
