Best hotel on the strip, Treasure Island (also kinda centrally located)
Best hotel away from the rat race.

They have a cigar lounge also.

When I go I rarely gamble if I do its at a bar on the floor playing video poker in the bar top. No need to wait for the cocktail lady. You can pick out your own top shelf stuff and enjoy.
My goal for going to Vegas is to chill by the pool, eat and do a little shopping. There is a Tommy Bahama outlet at this big outlet mall about 30 miles south.
If you have time visit Red Rock NWP. Nice over looks to hang out and smoke a stick.
I also recommend you not waste time at the buffets fighting the herd. You can have an awesome sit down dinner for a few dollars more at many fine places.
