I realize staying off the Strip and not at a casino are not even something you will consider while coming to Las Vegas but the Residence Inn at Howard Hughes Center is my new secret place for convention center trips. It's a real simple walk up Paradise to the show.
At night on Monday/Tuesday they have a free snack and beer for a Happy Hour in the dining hall. The breakfast is pretty decent as well. The hot tub is large but not the warmest/strongest jets you have ever felt. The tennis court they advertise is smaller than regulation size.
The rooms are fantastic and the mini kitchen is quality. Our room came with more than once flat screen and a bland 90's decor. Parking was no problem and you will have plenty of space while doing business in Las Vegas. If your ready to work and put in a good week of business in Las Vegas this is your spot. If you want drunken trouble and 24/7 gambling then this is not your place.
