I stay at Harrahs because of the location -- basically attached to the Sands Convention Center. Otherwise, I would stay somewhere else.
The place has aged and is in need of some serious updating and renovation. The rooms are pretty old and have obvious maintenance issues. Do they seem clean, however.
The casino is nothing special. They do have some of the latest slot machines, but the sports book is very small and there isn't a lot of table gaming.
We had an incident in which we were locked out of our room due to a technical problem with the door (not the door key). We waited over an hour at 11pm for someone to get us in the room -- and then we got little apology and no compensation.
The buffet is just o.k. and overpriced. The highlight of the place is probably the KGB (Kerry's Gormet Burgers), which is a pretty good restaurant.
In short, Harrahs is in a good location and is acceptable -- but it needs some work to be good.
