Welcome to this board MALCOM45!
I also stayed at the LAX Sheraton for the first time about 5 weeks ago. I previously used the Wesin LAX but the 2 last stays not up to my expectations so I decided to try the Sheraton on my next visit.
It was a very good stay, excellent staff, large corner room upgrade on the 15th (the same?) nice welcome gift. Will certainly return there on my next trip.
