Need help -21 & 22 year old

If you have the "funds" send them across the street to the Cosmo! They are the new "hip" joint for the "trust babies" and younger folks.
Many nightclubs in the area of where you are staying! They should have no trouble finding a decent party in many of these clubs that surround where you are located.

Thanks everyone for the responses......those are some great ideas and I will be sure to put something togehter for the girls, so they know some places they can go to have a bit of fun!
And because it will be great weather down there, I am sure they will find a pool they will enjoy!
If they are staying at Bally's can they only use the Paris pool or can they also use the Caesar's pool?

I'm not 21 or 22 but I still act like it at 35 when I go to Vegas. If they like the club scene then there are plenty to choose from - TAO, PURE, ROK (i believe at NYNY) - i've never been because I prefer to gamble. But if they prefer the more laid back "drink and have a good time" there is a Piano Bar at NYNY as well as one in Harrahs (i'm sure there are others as well). We went last summer and played at the tables right outside the piano bar at Harrahs and you could enjoy the music outside while the girls have a good time in the bar - just a thought. The piano bar at NYNY I believe is right by the Gallaghers meat display. If they are at Harrah's solo just have them be careful on the way back to ballys. This summer when we were walking back at 6am there were some shady characters out on the streets so make sure they keep their wits about them even if they are drinking - we've all seen the totally wasted girls that cant even walk in their short skirts and high heels. I'm sure they are excited! btw - you are one cool momma!

Make them gamble some and they will be hooked!

Check out the deals on Caesars website. They have and All Night Pass for $44.99 which gives you entrance to all the night clubs at all the Caesar's properties. There is also a 2 day show pass for $99 for over 20 shows at the various Caesar properties. Both are very good deals and may be what you are looking for.

The Cosmopolitan is like one giant night club and its right accross the street. If they are up past 3AM they can go to Drai's at Bill's Gambling Hall. Its a Las Vegas landmark. They dont open until 2AM or something.

I don't know, but i like those really drunk girls.
