If you don't get a "Go Room" don't go at all. The room they gave us had years old dried food caked into the carpeting, cracked tiles in the shower, the oldest shower head imaginable, peeling wall paper, a broken smoke detector hanging from the ceiling, a crappy old worn out bed, 10 year old tv, and a smell that would make your grandmothers undies smell like a flower conservatory.
When we complained about the room, they assured us that we would be taken care of with an upgrade to a "Go Room" free of charge. However, it was a total lie. The next morning they tried to charge us for the upgrade, were obnoxiously rude at the service desk, and informed us that the manager who had promised us the upgrade was wrong for doing so, and would be punished. Overall, this place should be torn down and the management should go back to hospitality school. If you're looking for a decent hotel in Vegas, look elsewhere. The Flamingo is a joke.
