The airfare seems high. The NWA website is showing fares for these days at $250 to $285 per person. I assume the package price is for two people.
I have never done NWA vacations, but I have used Funjet (www.funjet.com) once out of DTW and once out of Flint, MI. Check prices on all cities - FNT was about $150 cheaper than DTW for one flight, plus the airport is so much easier to deal with than DTW. Both times I found you could get a better deal by booking air-only through Funjet and going directly to the hotels website or other las vegas hotel websites. Check out
www.cheapovegas.com
This is about the best (and funniest) Las Vegas site I have found. They have profiles of every strip and downtown hotel. The trip reports are hilarious. You also may want to go to deja.com and search the alt.vacation.las-vegas group.
If you go funjet, beware of the Sun Country DC-10's they charter. They manage to get 10 seats accross instead of the normal 9, plus they rip out all of the first class to cram in as many seats as possible. They also use ATA, which I understand does the same thing on their widebody L1011. I'm guessing that all of the charter airlines do this. ATA 727s were not too bad, but still cramped.
I'm heading out to LAS in Sept. using NW miles to avoid the cramped coach charters. I'm planning on staying at the Flamingo because I can get a reduced casino rate for some play last year. Also great location right at the center of the strip. I have also stayed at the LV Hilton - which is nice but too far to walk to the strip. Last place was the Day's Inn Town Hall Casino - last minute reservation and cheap. Clean & quiet, but somewhat run down. Good luck on your searches.
