VEGAS

We did a whole day of roller coasters once....until I started feeling sick We went to the Siegfried & Roy zoo & aquarium, Fremont Street to see the laser light show one night & basically went to see all the free stuff in all the hotels - my favorites are the Treasure Island Pirate show & the Bellagio fountain show. Of course there are ALOT of bars & clubs too. My favorite bars were in New York New York (ironic huh )

Go hiking around Red Rock Canyon

Check out the Hoover Dam

SHOP

I was there for 3 days and we did a total of 30 minutes of gambling. We only gambled because we figured we were in Vegas so we might as well loose some money! We partied A LOT. Spent most of our time drinking or by the pool or drinking at the pool...it was a great girls weekend!

I live in Vegas and would suggest the following;

Bellagio. The fountains are breathtaking and tour the conservatory. They change it seasonally with fresh flowers and designs.

Have a romantic dinner at the top of the Eifel tower or another place is at the Voodoo lounge. You have a breathtaking view of the city at both places, but the voodoo lounge ( RIO) is also a club for dancing after.
Another nice place is to have lunch ( for cheaper) at Mon Ami a gabe. Its at Paris. Sit outside and watch the Bellagio fountains across the street.

take in the light show downtown .. the Fremont experience. Pretty cool. Free.

Drive out to Red Rock and take a hike, or just go on the 13 mile drive thru it. $5 bucks for the car to go in

See a show. I have seen Phantom of the Opera twice now. it is AMAZING... even if you arent 'into that kind of thing'. Known to be the best production of all the cities its been in thus far.
Blue man group. Another crowd pleaser and fun

Go to Harrahs. Carnival court for dancing and flair bartenders, then into the lounge to listen to the dueling pianos. They are a riot. People get into their requests and its a crazy good time.

If you like rides. Go to Circus Circus and the Adventure dome.
Ride the roller coaster on top of NY NY.
Ride the rides on top of the Stratosphere. VERY scary..LOL

Go rent some ATV's and go for a tour of different areas.
Rent some Jet skis and go out on Lake Mead for the day.
shop...LOL

Just walking up and down the strip is free and people watch. one of my favorite things to do :)

Hope that helps.
