We had 3 round trips with this company - Airport, DC and Kennedy Space centre.
Competitive rates, very friendly and personal service, 3 different drivers but all went the extra mile to chat and be friendly, always prompt.
Also always had the option of prepaying your gratuity prior to travel with a registered credit card and as such no additional gratuity was expected, unlike some other companies.
1st time we have used them and we will definitely use them again - tried to sell the board to them, so if you use them please mention where you heard about them .
The last chap we met at the hotel I called out accross the car park
'No, I'm Mario.......maybe at the weekends though'
