I've stayed at Sheraton and Westin numerous times over the past 25 years, never
stayed at W ( I hate the brand and will never go back), and only attended a wedding
at Le Meridien during it;s soft openeing - never stayed there.
Sheraton and Westin are more convenient for my business meetings - they are close
to the offices I need to visit. I didn't like the look of Le M during the wedding I attended.
While there have been times when the Westin was better than the Sheraton, the past
few years I find the Sheraton superior to the Westin.
