I can't believe Marriott does not have an IPHONE app!!! Every major hotel chain has an Iphone app as well as a smart phone website. When you call Marriott they direct you to use the Website smart phone enabled site. This is not and IPHONE app and there is no reason why they should not invest in the Iphone app. My guess is that the management team that decides if they do an app just does not understand how easy and nice an Iphone application would be. Marriott needs an Iphone APP!!!!!
