The New York Marriott Downtown is by far one of the worst offenders of this.

After checking in, I realized that I was not offered the welcome gift or received any details of the lounge. (I stayed here about a month back and was told the lounge was closed - I continued to assume the same). I chatted with the hotel saying I wanted to claim the guarantee. The hotel called my room and the manager said to me that he was "standing next to the agent who checked me in" and assured me that the agent had told me that the gift was points only, and that the lounge was open for breakfast Monday to Friday. (this was a lie). I replied to him that I was not offered the other choice of the $10 F&B credit, to which he told me that they cannot offer that right now because the restaurant is a third party. I instantly replied that the hotel has a mart/pantry and would happily sell me a bottle of water for $4, why can't I use the credit there? He told me that they just cannot offer the credit now and that he is denying my claim. Of course I said I would open a case with corporate instead. Well now corporate is giving me the runaround saying that the hotel is allowed to only offer me the points, I had received a complimentary upgrade from a single to double room (I always had booked a double), and that I received 2 bottles of complimentary water (uhh no, and what has this got to do with the guarantee).

In order to not have to offer the 750 points in lieu of the lounge/breakfast, they open the lounge from 6 am to noon, and offer breakfast 6:30am-9:30am, only Mondays to Fridays.
