Just completed a quick stay at the LAX Marriott in Los Angeles, CA. Spent 2 weeks in Palm Springs (Marriott Desert Springs) and stayed overnight before flying back to New York the next day.
Could not be more pleased with everything. I received a welcoming email from them two days prior and when we arrived at noon was upgraded, without asking, to the concierge floor. As it was Saturday I mentioned that I knew the lounge would not be open. They said they were sorry and gave us two vouchers for buffet breakfast the next day at their restaurant.
The cost of valet parking is steep ($32.50) but it was managed very well. When we called for the car from our room it was waiting for us when we got downstairs.
The facilities are great -- hairdresser/barber on premises, restaurants, business center, workout rooms and a simple beautiful landscaped outdoor pool area.
Highly recommend to anyone needing to stay near the airport in LA!
