Overall very good and an enjoyable experience.

Check in was ok but was made to give a credit card deposit of $200 even though I paid in advance, the way they refunded it meant I now have an oustanding CC bill beware if travelling from outside the US as you will lose out.

The room on the 27th floor of the Mardi Gras tower was everything i wanted spacious nice bed and bathroom which was fine. the view was not the greatest but having been to vegas many times before hardly bothered me.

The facilities at the hotel are fine, try the spa the facilities are good nice gym sauna stream room etc.
the pool is fine , I am not one for lying by the pool bou swim and the poo was good first thing in the morning to swim in
The buffet is the best I have eaten at in veas in a long time, the cafe was ok and I never tried the rest.
I enjoyed gambling in there , but would prefer no smoking (when will they finally ban it) as it can get quite smokey in there.
Location is superb no buses or expensive taxis to catch you can walk everywhere from here on the strip.
I would definetely stop here again

First night, no hot water, not even warm, they moved us next day, but because the room was not ready, they had to take our luggage to bell station (another tip), we were told to come back around 4, not to stand in line, just walk up and ask for key. I did this, only to be screamed at by one of the front desk clerks, who had no business working with the public, which embarrased me and actually made me cry, because I was sick, running 103, the manager tried to make me happy by giving me a $30 room service credit, which at check out they tried to charge me. The next 6 nights were in a room that the AC sucked and would not go below 78, but the front desk people are the main problem, they are rude and I would never, never go back. Harrah's your hotel is really going down hill.

My friends and I stayed in room 722 of the Carnival Tower June 25-27, 2009.
The Good: Location! This hotel is center strip. Easy walk to other properties and there is a "food court" right outside of the door. We did not eat there. There is a Starbucks right off of the elevators too. Room was fine for 3 guys. It is a little small but we didn't have much with us. Room was clean and has a safe. Harrahs is willing to work with you on price to get you in the door too.

The Bad: Self parking garage is confusing to enter. Table limits were $10 even on slow mornings. Casino Royal is right next door with lower limits. View from this room was of the parking garage. No big deal.

We had a room in the Mardi Gras tower, it was a newer room with a flat screen tv and even one in the bathroom. The room was very nice, a little on the small side but really didn't care because it was just me and the wife. Bed was comfortable and the location can't be beat (Center Strip). Very good value.
