Limo service from Orlando airport to WDW costs from $70-$90 round trip (plus tip). It's more for a stretch limo. If you have 3 or more in your party a limo service is often a better deal than the bus (shuttle) and it is more direct and more comfortable! The driver meets you at baggage claim, helps you with your luggage, will stop at a grocery store for 15 to 30 minutes (you need to prearrange this) and will finally drop you off right at your resort. At OKW, I have been taken directly to my condo. A limo service gets your vacation off to a great start. We set up our first one clandestinely. The kids were taken by surprise when there was a uniformed limo driver with our name on a card.
I have tried Atlantis, Tiffany, Happy and others. I was less than impressed with Happy who precharged the tip, then showed up in a van because on of their town cars got hang-up waiting for another passenger. I would surf the net for the best deal or coupons. I generally tip between $10 and $20 per trip depending on the service..
