I always like staying at the Cosmo. It's a beautiful hotel with great restaurants and a pool with a nice view. The rooms can be spacious, I like the Boulevard tower as it's closer access to everything. A note for those who want the rooms with views of the strip- the views are spectacular BUT even 57 floors up you will hear all the noise of the strip which is loud and you won't be able to sleep unless you have had a wild night of drinking and simply pass out. If that's not your plan, don't face the strip.
