Suggested LV places to visit depends on your age, but I'm thinking that you are under 30, so here are some suggestions ......
Meet the ladies......
The Rehab Party on Sundays at the Hard Rock. My last visit - you had to be a hotel guest to get in, but that may have changed this late in summer.
The Palms and their Fantasy Suites and nightclubs - Ghostbar, Moon, and the Playboy Club (Last time I checked there was a $40 cover charge.)
Just about all the nightclubs in the Strip casinos, but pick up some free passes from some of the guys handing them out along the Strip between Paris and the MGM Grand. A small tip will save ya $20 or more. Take as many as you can get and visit each and every one of them if you have the time.
VooDoo Lounge at the Rio for good looking ladies and Strip views.
NOTE: Lines into these nightclubs start forming up around 10 pm, so expect to do some waiting unless you can get some line passes. Ask around. Some of the better bellmen and valet guys might be helpful. If them do come through - TIP 'em!
Tanning....
Great pools here.
Best pool is at the Mandalay Bay with a wave pool, a lazy river, a poolside casino, and a private European style pool that requires admission.
European (topless) pools are also available at Caesars and the Wynn and possibly a couple of other hot spots.
Best pools are at MB, Caesars, Bellagio, Mirage, the Wynn, and Hard Rock.
Check out the new pool/shark tank at the Golden Nuggat (downtown)
Best Eats .....
Good food all over town but I'll recommend only those I prefer (meaning that the food is good and relatively inexpensive).
For a real cheap, good meal, try Ellis on Koval behind Paris Hotel Casino. The Steak Special is about $5, but you won't find it "IN" the menu. Just point to the photo of the steak dinner on the menu cover and ask for it. Or even better, try the prime rib (about $8). The GIMMICK here is that you have to wait for a table even if the place is empty and the service is not the best in town. The "Wait" is to get you to do some gambling, so sit at the beer bar and have some great $2 casino made brews. After dinner, rip off that $5 Match Play deal on the placemat and take a chance on one of the tables. It's a decent bet.
Oreans Buffet is good and cheap but the coffee shop has a great prime rib deal at about $13.
Any buffet on the Strip will do their best to convince you that their $24 buffet is the best in town. Don't believe it. A $12 buffet will be just as satisfyng.
If you want a good and large breakfast, try the Peppermill a few doors down from the north edge of the Wynn. Always had good meals there.
If downtown, try Triple Georges'.
Sightseeing ......
Do the walking tour through all the major hotels.
Take the monorail tour on the backside of the Strip.
Watch the fountains after dark in front of the Bellagio.
Go to the top of the Stratosphere and ride all three "rides" at nite.
Visit downtown at nite and watch the Fremont Experience. (Once is more than enough).
Gambling ......
Play smart and gamble cheap. Look for low minimum tables. Here's a couple ....
Slot's O Fun next door to Circus Circus has $1 blackjack. (One table, usually packed, so go early or expect to wait.) They also offer $3 games.
The Casuria Hotel Casino (East Flamingo - one block off the Strip) offers $1 Craps from 5 pm to 10 pm on Monday/Tues/Wens/Thurs evenings. (And the Ellis Island dining spot is almost right across the street on Koval Lane.)
Not too many $5 tables on the Strip so take your gambling action to the neighborhood joints like the Orleans, unless you plan to lose a lot of money real fast or feel extremely lucky.
NOTE: Penny machines can be profitable if you can be satisfied with a $5 win and walk away when that happens. Play a twenty and if/when it reaches $25, take a walk.
If you have the tikme, check out the Hoover Dam and notice the unbelievable construction that is underway to take the Nevada - Arizona traffic off the dam. This just might prove to be the wirhth wonder of the world.
And Red Rock and Valley of Fire.
Have a good time
