Lucky, I love Vegas! You'll have so much fun. Definitely just get out and walk the strip! So much to see, and it'll take most of one day just to do that. A lot of places you'll go will have a little coupon book with special deals for attractions or shows, like 2-for-1 deals... like if you take a cab from the airport they should have some in there. The last time we went, we stopped in the Luxor towards the end of the strip (the pyramid shaped hotel/casino) and they had a ticket desk where we were able to pay one price (something like $50/person) and it allowed us to go to 3 different attractions. You choose from a list they have, and we picked the Titanic exhibit there at the Luxor, the CSI exhibit at MGM Grand, and this silly Spongebob 4-D ride at Excaliber.
MGM is a really great hotel & they have the lions all day which are fun to watch. The Venetian is REALLY beautiful where their shops are. Planet Hollywood is also fun to walk around. City Center near Aria is way fancy, and just something to see!
Also, I recommend spending the money to take a taxi down to Fremont Street, or the old strip. Taxi fare was about $23 each way, but down there they have the 4 Queens, Golden Nugget, Binion's, etc... and it's the covered street with the "tv" going over it and at night they play different entertainment bits, or shows... and there's usually a street entertainer down there.
Have fun!!!
