There are car services that give you the greatest of service. You might stay away from the bigger car services, as they normally used sub-contracted drivers. That is not a great policy. There are many excellent services.
One poster, on the boards, has been on the boards to long. She has trouble realizing the difference between fantasy and reality.
Of course the "Glowing" endorsement comes from a driver of a car service.
Some of these links are old since I haven't bothered to do this in a while.(And of course since Edd did not write the posts below they will be "fiction" In his world only HIS postings are "fact"

Happy Limo
http://www.disboards.com/showthread.php?p=6720727#post6720727&highlight=happy+limo
On September 2, 2005 I made the worst mistake of my life by going with Happy Limo service. I took a chance and thought I was making a good choice to reserve with them. This is the one area that any Bride doesnt want mistakes with and I got them all. I instructed the reservationists that I DO NOT want a HUMMER. My husband hates the vehicles and he thinks they are tacky. I also asked for a WHITE excursion. We are not at a funeral here or a prom this is a wedding.
May 19th in Orlando at this time and called 2 times to confirm the addresses and pick up times. I also instructed the reservationists that I give her the directions personally so there are no mistakes and they assured me that they have it under control and they have it all handled. At this point in time the day before a wedding the company should have checked out their equipment to find any problems if there are any at that time. I was instructed that my limo the White Excursion was ready to go and I had NOTHING to worry about because after all there slogan is the last thing you should worry about is your limo.
On the morning of May 20th I went ahead with my day as planned after all it is my wedding it should only happen once in your life and so you look forward to every minute of the day. I had no idea that I would get a call from my husband to be at 1:35 and the limo is not there yet. Still not there at 1:40, I was starting to freak out. Finally at 1:45 my husband calls me to say they are leaving and that the Limo driver has no idea where he is going.
At this point in the day I am having a nervous breakdown because not only is my limo 30 mins late but I also have no video footage of me since my video service was in the limo driving in circles lost. The Video people told me once she got there that he was lost coming back.
My video service once they got there was supposed to take 5 minutes of video of me with my family and my bridesmaids fixing my dress and getting last touches. But instead the limo company being late over 30 minutes I have nothing to show of video footage.
Once the limo arrived the first thing out of my mouth was what the heck is that in the front driveway???????
I asked for a WHITE excursion not a black HUMMER. As previously stated in my letter when making my arrangements I told them over and over that a HUMMER was not acceptable to us and we felt it was not what we wanted on our day. I again was NEVER notified of this switch and was left to be shocked and upset on my wedding day.
We are not at a prom here we are at a wedding. At this point the company was so late what was I supposed to do, the company tells me now why did I take the service if I was so unhappy with it? That line gets me every time. Why?? Do you ask, I took the limo because I had 11 people with me and no car to get there? I guess I should have asked for a taxi to the church or maybe we could have waited at the house till 6 and not get married at all.
Once the wrong limo showed the fun really began. It was not only 98 degrees that day but the limo had no A/C at all. The company was under prepared, no drinks, no customer service I had to have my bridesmaids help me in the car cause the driver was on the other side of the door not offering a hand at all. By the way he was in Cocco Beach and hour away when he should have been picking me up.
At this point my make up was sweating off my face and my hair was begging to fall from the heat and moisture in the limo. We had to open the window and that caused more damage than good. I had no video footage of me since I was steaming mad and I am so upset and hurt that I cant think back at that moment in time and think of joy and happiness that instead I feel hurt and anger that they took this away from me.
My grandma was in the car not feeling well at all and feeling signs of heat exhaustion.
Once the limo driver got there I had to run into my service and at this point it was 35 minutes late. I had my ceremony cut short and things cut out of the service because of them.
After the wedding I had some photos but lots of photos that I had paid to have done were not taken because we were asked to leave the church by the priest since there was a service after ours. While pictures were being taken I was sweaty and didnt look my best.
After we go outside the limo was not there, they were getting ice and waters, and NO red carpet and NO just married sign, more photos which I didnt get that I wanted. The driver had turned on a movie for reasons I still dont know. He had on Analyze that with Billy Crystal. This is a Rated R movie and not appropriate for children. Once I got in the limo again no help at all from the driver not getting in or out for that matter. We settled in to go and stop near the hotel for our champagne toasts. But on our way there the girls were watching a video and my dad had pointed out to me that there was a sex scene going on and we screamed to the driver to turn it off. He said to us I cant he said we have to but we had no idea how so another reason that I needed to be distracted from my day was to make sure that these kids were not in harms way from watching movies they shouldn't be watching.
Limo company that cannot be named on here
Dad asked to speak with his manager, and he said that he was the owner of the company and could do whatever he wanted. Needless to say we canceled and rode back to the airport on the Magical Express. I have since filed a complaint with the BBB and emailed another disney site to tell them. Use this service at your own risk, especially if you would need to change plans later in your trip.
Tiffany Towncars

booked with Tiffany based on the recommendation of a unofficial web-site. Normally I use a rental car but thought this would be the better choice since I would be traveling alone with my 5 & 6 yr olds until my husband could join me on 7/1. I asked for multiple confirmations via e-mail & phone. $172.00 total - 6/28 Pick-up of 3 from MCO to Contemporary, store stop. 6/30 pick up of 1, same directions. 7/2 transfer 4 to Universal's Portofino. 7/5 back to MCO.
The driver was courteous and a welcome sight after a tough flight however, he didn't stop at a store and, he charged he the full amount upon arrival. When my husband arrived he then charged him $50 more to $222. I called and tried to get them to adjust the price and they said they would. When my driver came to pick us up for Universal he claimed no knowledge of the situation and complained that the office had made the mistake. Not wanting him to 'forget' to pick us up I made no waves, yet.
7/5 on our return trip I inquired again and got the same run around. Just for fun, our driver threw in some anti-american rhetoric criticizing our system of government. We were not happy, free speech is fine but I was paying for my trip:< At the airport our driver refused to reimburse us so I gently suggested that he try and work things out at his office and take our as yet unpaid tip out of the difference.
Never again
And then there was the Limo driver who cussed like a sailor from MCO to the port in front of my friend's young children. Drove about 100 MPH and anytime anyone in front of him went "too slow" he called them names and gave them the finger. She now rents a car and parks it at the port LOL!
Now there are good reviews for all of the companies too, but for me I have decided the risk of a bad expereince is not worth it.
