I would be happy to return to the Renaissance Las Vegas Hotel on another visit to town. If you prefer to stay a little off the strip this hotel would be a perfect spot for you. It's also right off the monorail and just a $10 cab ride to Caesar's Palace.
It has great access to the convention center. It's also ideal for the business traveler as it has a business lounge and additional meeting rooms available for use. The staff here is over and beyond friendly and willing to accommodate their guests. Rooms are nicely appointed and they have a large work out facility.
My only complaint here is the pool area. It's what I call a "make believe" pool that gets very little sun. They also have only one restaurant and if you're staying at the hotel for awhile it would be nice to have a few more options but.....then again the strip is always nearby.
