Yup
Couple suggestions:
1) any money you'd like to keep, leave it at home
2) walk the Strip and look at the free shows
- Caeser's statues
- volcano at Mirage
- Pirate ship at Treasure Island
- fountains at Bellagio
- Aquariums in Mandalay Bay
The list goes on. It is unbelievable how much there is to see and do, much of it free
3) If Shannon enjoys shopping, keep her out of Fashion Show Mall. It is a mall at the middle of the strip and it can put a serious dent in your credit limit.
4) make sure you see the strip at night. The lights can not be described
5) if you have time, go downtown and see Old Las Vegas and the Fremont Street Experience.
Don't be fooled by the distances. From the Sahara (north end of strip) to Mandalay Bay (south end of strip) is four miles. A lot longer than what it looks.
I always enjoy watching the people on the flights and airport going and coming. It is amazing how quiet those leaving are.

Have a good time
