I've traveled the world and stayed at a number of 3,4, and 5 star hotels, and I've never had such a poor experience as I've had at the Biltmore.
When my wife and I first arrived at the hotel there was no bellman to take our luggage to our room + we had to wait 15 minutes on line (only 2 people ahead of us) just to check in.
We had the buffet breakfast the next morning and it was $25 per person for a very average buffet. The first was not fresh at all.
We had to call room service twice to request that they clean and service our room that day. In every other 5 star hotel I've been to they cleaned our room 2-3 times a day, and we never had to ask them to do it.
It gets worst...
We book a conducted tour of Miami for the following day, the concierge flat out lied to us. He said the tour would in a small van with at most 7 people, and not a big tour bus with 50 people.
So we booked the tour, $75/per person. Long behold we were picked up by a big tour bus with 50 people!?!
I've never had a concierge flat out lie to me like that. It's outrageous.
My wife and I were completed shocked by the complete lack of service and professionalism at this hotel, if you ask me it should be stripped of it's 5 star rating.
If you're considering staying here, I would strongly recommend against it. Save your money and go to a Westin or the Intercontinental instead.
