November is a great time for deals in Vegas. Keep you eyes open.
As for the best location, I would avoid the north strip (Circus, Circus, Stratosphere, Hilton, Riviera) because there is a lot of construction going on there now. You will have a longer walk to get to most places. However, there will still be plenty to do in those areas.
As for amenites, most places offer the same ammenities. High end places like The Wynn, Venitian, Paris, and Caesars will offer a lot more, but those rooms are the most expensive you will find.
Places like TI, Planet Hollywood, Luxor, Monte Carlo, and MGM are a bit cheaper. They are decent places. The amenities are all comparable to each other.
Imperial Palace and Circus Circus are two of the most popular places to get deals. But everything is very hit and miss. I have heard stories of dirty rooms, smell of mold in rooms, bath tubs backing up. These things are still rare, but they seem to happen more often at the lower priced hotels. The amenities are nothing special, but the deals are excellent. And the location of the IP is excellent.
If you are trying to find a good balance, I would suggest looking at:
-Tropicana. Very good deals, very old school casino (some people like it, some don't. Either way, the place has a nice charm to it) Amenities are nothing special, but decent.
The last three are a bit more expensive, but not by much. The hotels are a lot more modern.
Check out each hotel's website and sign up for their e-newsletter. Novemeber is a slow time for Vegas, so rooms will be cheaper. Lots of places send out e-mail only deals. If a week is looking to be much slower than expected, then they will often send out an e-mail letting you know of a cheaper price. Each casino is very good about not spamming you.
