    "We assumed that this hotel would be as nice as Margaritaville in Florida, that was a bad assumption. We booked a one room suite, not a cheap room. Our first smelled like a broken sewer pipe, we lasted 20 seconds. Front desk gave us another suite, TV had to be replaced, the 4 chairs at the dinner table were all stained/soiled. I would not recommend this place."
