I have been a loyal guest and proponent of The Flamingo Hotel & Casino for nearly Twenty Years. In the past, I came to enjoy your property for the history, customer service and friendly policy on dogs. Conversely, during a recent stay, over the Christmas Holiday, my entire experience was disenchanting to say the least. After driving through oppressing Holiday traffic, I arrived to find both the Valet and Self parking (unapologetically) full, leaving me to locate parking off site (at another hotel), paying non-guest rates, not to mention the inconvenience. As a whole, the attitude among the Staff was unhelpful and brusque. I (along with other guests I briefly spoke with in passing), felt as if the simplest of requests or inquires were impositions upon the staff. This was a complete change from my previous stays at The Flamingo. As a frequent traveler both professionally and personally, I use my American Express Platinum to book all travel in the instance I should ever encounter any issues or for any reason need to utilize their customer service. Following this wearisome and disappointing experience I feel it my responsibility to inform Amex, along with -fellow travelers of the substandard Customer Service and unavailable parking.
