I've always felt that Marriott was withholding by not putting the email addresses of hotels on their site. It's very irritating. Marriott also used to have a program called "along the route". It was a great program. You could map out your route for a road trip and all of their hotels would show up along the way so you could organize which hotel you might want to book. Now, if you are doing a road trip, you have to figure out where you might like to stay and guess if there is a Marriott in that town.
