I reckon you'll cover Vegas in a 24-hour period, though if you like nostalgia, visit the Old Strip, great pawn shops and vestiges of the original Vegas. If you ate looking for a quiet place to stay, try Trumps hotel. It's off the strip, and no slots or gambling, but walkable to all the casinos and entertainment.
Make sure to also include a decent amount of time to stop at Hoover Dam on your way to the Grand Canyon. It's 250 miles, so don't do it as a day-trip if you can avoid it. Spend at least a night. Here's the national parks link with more details:http://www.nps.gov/grca/planyourvisit/directions_s_rim.htm
Check for any permit or passes required if youbwant to do any particular trails or do an overnight in the Canyon. Viator.com would likely have a great offering to consider for packages like that, especially if you are short on time to plan and when on the ground (though I'm inclined to piece it all together solo.) almost 7 years ago
Right now is a fantastic time to go to Las Vegas due to the economic climate. I get emails every day concerning discounts and offers. Most of the resorts are climbing over themselves to get visitors in!
There are also plenty of attractions in and around Vegas, as with the last reply, Hoover Damn and the Grand Canyon should be on your list. There are also some fabulous shows most offering 2for1 tickets.

Answer below is great and I also recommend trump tower, it's luxury, great price, no smoking, no casino, and next door to the shopping mall. Go to grand canyon by helicopter, there a number of companies, book early, and go early, so you can get on the sky walk easy. It's a great way to do the grand canyon and an experience I wont forget. Las Vegas is awesome! Enjoy! almost 7 years ago
