Marriott shows rates with taxes and ALL fees (price transparency checkbox)

I stumbled upon something really cool last week. Sometime recently (I don't know when), Marriott added a new price transparency checkbox to their web-based property search. Checking this box changes the display to show prices with taxes and resort fees included. This is an awesome step in the right direction.

In an ideal world, all-in pricing would be the default view, but with competitors not yet matching this feature it's understandable why Marriott has made it optional. At the time of this writing, this feature appears to be available only on the web and not via the mobile app.

Here's an example of how it works. I searched for St. Regis or Autograph Collection hotels in New York City. By default, I see the rates before taxes and fees, but I also see the new price transparency checkbox:

After clicking the price transparency checkbox, I get an updated display. Note that the St. Regis' displayed price jumps from $724 per night to $892:

When I select a property (the St. Regis, in this example), price transparency follows through to room selection:

Then, after selecting a room, I click to view a Summary of Charges. This shows that the all-in price includes the $50 per day destination fee:
