Good Location, Some Problems, Should Rate Higher
The LAX Marriott is a massive property located near the entrance of the airport. Free shuttle service is available to/from terminals. When I arrived at the property I was shocked to see a $35 valet rate, and the bargin rate of $27.50 to self park. I understand that the hotel needs to be vigilant with parking being so close to the airport, but $27.50 to self park seems exorbitant. I soon realized that the self park lot was already full due to an on-site wedding. The valet area was in total chaos there didn't seem to be anyone in charge. I had no confidence I would be able to retrieve my car in a timely manner so I decided to return my rental. National Car Rental provides a shuttle to local hotels which was very convenient. Upon my return to the hotel the situation had gotten much worse as now cars were snaked through the entrace to the hotel. The driver had to drop me off at the entrace rather than get trapped in the parking lot chaos. The check-in process was a little better but the lobby was filled with people, luggage everywhere, bellman struggling to keep up. 
My room was at the furthest point you could get from the front desk. I walked and walked and walked. The room itself was smallish, but well appointed. Like most Marriotts, even as a business traveler, nothing is free. No free internet, no free water. My room was on the pool and I did experience some pool noise until the cold weather drove everyone inside. The bed was comfortable and fresh. Flat screen TV and furniture were in good shape. Decent work station with good lighting. The bathroom was also in good shape with a good powerful shower with plenty of hot water. Nice towels and amenities were typical Marriott. The room provided a restful evenings rest. Shuttle was very crowded and filled up fast in the morning. Flight crews and a couple of families with small children, luggage, car seats etc. I would recommend you be in the lobby on time so you have a spot.
I would stay at this property again for an $89 - $100 rate but with all the add-ons and commotion I don't think anymore than that represents a value. This property should rate higher but I can based my experience.
