Since I used to go to Vegas once a month for work and some pleasure, I consider myself a somewhat expert on this topic and here are my suggestions.

1. RENT A CAR!!!! taxi cabs in Vegas are getting very pricey. U can rent a small car from hertz and it will cost you $29.99 a day.

2. Stay at Paris. For the price, its the best hotel in Vegas and is very centrally located.

3. If you can't stay at paris, go to MGM grand. Prices are reasonable and the rooms are very clean

4. GO SEE HOVER DAM!!!!
don't ask why. just do it!!!

5. Alway and I mean always have a loss limit before you sit at a table. Don't let gambling ruin your trip. I ruined mine several times.
