We stayed at the Marriott Wardman Park last August and found it to be a nice property.
However, my two most vivid recollections are negative.
1) When I went down the hall to grab a soft drink at the Elite member's hospitality room, I was chased out of it by the attendant because I wasn't wearing shoes. I walked back to my room and dutifully donned my shoes (hope I didn't step in you-know-what at the zoo) and returned to get my Pepsi.
2) When I attempted to retrieve my "special free gift" at the Marriott Vacation desk, I was abruptly told by the agent to wait until he was finished with the previous guest (he must have understood that I just wanted the gift and not the sales presentation). I waited and then he reluctantly gave me the gift (one Marriott logo golf ball) after confirming that I didn't want to hear his spiel. BTW, the free gift was promoted as a no-strings-attached, no-consideration gift (i.e. just like the old meanings of "free" and "gift").
