This is an unfortunate review to need to write because I have stayed here many times previously.||I guess I should state that whenever you visit Miami, there are two situations that you need to be leery of: 1 - there are a lot of international tourist who are not accustomed to tipping and 2 - there are a lot of people who travel to Miami, run up huge bills, and then leave town without paying them.||When I checked in, my stay was for 6 nights. As is customary in Miami, when you check-in, the hotel charges the price of the room and $100 per night per incidental. Again, this is routine, and the $100 per night in Miami is fairly typical. What is different is that as a result of item 2 above, this hotel (which they do not inform you about when you check in) will charge additional charges directly to your credit card when the remaining deposit amount is less than $100 per night. My first night there, I ate dinner with a coworker. The bill, after a mandatory (because of reason 1 above) 18% tip came to $237. I charged this to my room. When I got back to my room, I noticed that there was a $234 attempted charge on my credit card which I thought was a mistake, so I paid it no mind. I went to the hotel restaurant again the next night, had dinner which again included my mandatory tip, and the bill was $80. I was told that when the server tried to charge my room and was unable to do so. She went to the front desk, had a conversation with the individual there, and came back and told me everything was ok. This morning, I tried to charge coffee to my room, and again, they said they were unable to do. Finally, I went to the desk myself to figure out the issue. ||For perspective, I stay in Hiltons for work approximately 115 night annually, so no, this isn't my first time in a hotel nor is it my first time at this property.||When I went to the front desk, a manager (Andy - which did not match the name of his name tag) was called over, and the manager stated that the initial charge didn't work. Mind you, at this point, I had been at the hotel for 2 nights. So I stated that if the initial charge hadn't gone thru, they would have asked me to remedy the situation or leave the hotel. That clearly couldn't have been the issue, and I asked him to check again. He then told me I exhausted the incidental charge. I said that some simple arithmetic would determine that was not the issue either. Then he said my card was declined which again both couldn't have the case and wasn't the issue here. I finally had to leave for work, so when I called back, I asked for a different manager. After being on the phone for 20 minutes, I was finally put on the phone with another manager who essentially explained that when you charge incidentals to your room (the amount that was being held from when you checked in), if the remaining incidental charge is less than $100/night, that amount is directly charged to the credit card. What he tried to avoid saying, but was later clarified by Hilton, was that the hotel had been burned by other travelers, so they instituted this rule which they do not explain upon checking in at all, to protect themselves. Interestingly, when I called Hilton to try and move hotels, the individual I spoke with seemed all too happy to explain to me how frustrating and difficult the charge back process is. ||As some other service failures, the soap that they provide in the room was empty on the day I arrived and remained so until I checked out, and the valet attendants pay very little attention. I called down to get my car about 15 mins before I reached the valet station. I was told that they would need 5 mins, so I purposefully gave them extra time as Miami tends to be slower with these types of things than other places, and when I got down there, they had no idea that a car was even requested.||All in all, I am forced to stay an additional night because my checking out after checkout time would inconvenience them, but I will be checking out tomorrow morning. I will not stay here again, and I would caution anyone planning on staying there to plan accordingly as they have rules that clearly do not wish to communicate.
