Used Lansky today based on recommendations on these boards. I booked about 4 weeks out and prepaid. Great experience. Driver was waiting for us at baggage claim, helped with bags, gave us bottled water in the car and a 20 minute grocery stop at Target(wouldn't be my first choice but we got what we needed). Tip is included but DH can't help himself and tipped $20. If you are not familiar with LA and the traffic, be prepared for fast driving on 6 and 7 lane highways. I mean EVERYONE was driving at least 75 mph, weaving in and out of traffic. Our driver was great and stayed in the commuter lane but I'm glad I don't need to get in a car for several days. I'm also glad we decided to use a car service instead of a rental car. We would still be trying to reach DL.
