I am going to Las Vegas on July 27. Is there any promo codes I could use to get a good rate on a hotel?
The Luxor is a very nice 4 star hotel
Luxor - Special "MVP" - Promotion code "LDNON10"
phone reservations - 1-888-777-0188
"any suggestions" - since you're driving and will have your car, why not stay off the strip, it will save you a lot of $$.
Orleans>1 mile west of the strip on Tropicana
Stratosphere>North end of the strip
Gold Coast>1 mile west of the strip on Flamingo
To compare room rates
This site uses "travelaxe" which compares 15 or so of the top discount travel sites - this should give you a good idea or the rates and many LV hotels will price match.
If you just want to try one travel site - IMHO this one generally has the best rates.
