We just completed a 1-night certificate stay at one of our favorite SoCal Marriotts, the Long Beach Marriott by the airport. This hotel continues to impress us by providing free breakfast buffets on weekends and holidays when they don't have to. Also, they keep their concierge lounge open (but unmanned) on weekends for water/soda/coffee and just hanging out. They are in the process of renovating their first floor areas, but this by no means detracted from our stay. If anyone is ever in the area, I can't recommend this place enough. It's freeway close, and a good base for exploring LA and Orange counties. Also, it's a Cat 4, making the use of those certificates easy!
This is "A real deal", of a location. You can get to many of the interesting places easily from here! I enjoy dinner at Churchill's on the Queen Mary, 555 Steakhouse, and the downtown Long Beach spots from the Marriott.
