Where on the marriott website can I found the hotel grades?
You know--the 1-8 they are assigned.
Each property will list their level from one to eight on their home page. When you do "Find" simply check on the hotel name and it will give you their home page. If you look at the "Hotel Fact Sheet" it's normally listed there.
