I have manage to stay in a few different locations now and some extra data points. I do have an ambassador but I have not used him for any requests.
First up was Westin Vancouver in September. Basically like reported earlier - given the biggest suite on that floor and it was a high floor. Then again it was an all suite hotel.
Then it was in Sheraton Hong Kong in September right when we got hit by Typhoon Mangkhut. I was given an corner suite that has partial Oceanview with exactly ONE bed. I was in Hong Kong for a traditional Chinese funeral and may have important relatives in China that may want to share my room. So I downgraded the room back to my usual Ocean view room on a high floor. Everything seems relatively similar to when I last stayed there pre-merger.
Mid October, I had a stay in Delta Victoria Ocean Pointe Hotel. I just need a single night on a Wednesday and needed to attend a early meeting next day. So basically checkin at late night and check out early morning. This is my first time staying in this Marriott brand. Before the merge, I would rather drive to stay in the Four Points outside the city core than staying in a Marriott. In my first stay in Marriot's Delta, I received possibly the best upgrades this year and definitely one of the best upgrades I ever had. They gave me a penthouse suite on the top floor. The room has two floors. The staff recognize my status with a slight error of forgetting to mention my welcome gift. I suspect this upgrade was beyond what is necessary within the program. I understand there was a "Welcome Gift Guarantee" where if staff forgot the welcome gift, I can demand $USD 100. I didn't want to discourage the upgrade they have done nor appear ungrateful and I hope they do the same to other Platinum members. So instead of asking for any compensation, I just mentioned it at the front desk during check out and emailed my ambassador to follow up on the welcome gift (ie 1000 points).
There were two bathrooms - one on each floor. This is one of them.
