This thread caught my eye as I need to stay near LAX for the first time in a long time. I used to stay at the Westin when it had the Jacuzzi suites -they were quite nice. As I recall you did fill them fresh each time. It was great to be sitting out in the tub with a nice scotch watching the activity at the airport.
The Westin was not on my list to book as the last couple of times I did stay there it was not pleasant. However, reading the recent comments here and the great participation of the property representative, I'm going to book it to see what the improvements are like.
