If you are planning a trip to Las Vegas and would like to include some golf, there are some things you should know beforehand. For instance, Las Vegas is so incredibly hot between June and September that playing golf can actually fall under the category of a high-risk sport. I have never been able to enjoy a round of golf in triple digit temperatures.
On the other side of the coin, greens fees are significantly less in the summer months, and if one starts very early in the morning it is somewhat bearable. In my opinion, there really are only a few good months of the year in Vegas to enjoy being outside for 4 to 5 hours, that being October-November and April-May. Having spent plenty of time in Vegas during the winter months, it can get quite raw and windy, not what I call good golf weather.
As far as the golf courses themselves, Las Vegas has the proud distinction of being home to the nation's most expensive courses, at $ 500 per person to play Shadow Creek, Cascata and Wynn's. I can not say that I'm in the financial league to have played any one of these courses, but I hear that Shadow Creek and Cascata are really something else. The Tournament Players Club in Summerlin is also one of those special courses, and it can be played for a bit less, although not a lot less. If you want to get a decent tee time, you have to stay at the JW Marriott at Summerlin. In fact, with all of the many different golf courses in Las Vegas, there are only two bona fide golf resorts, Lake Las Vegas and JW Marriott in Summerlin. The two golf courses at Lake Las Vegas, Reflection Bay and the Falls, are supposedly quite awesome.
Las Vegas has a nice range of municipal, semi private and public courses, usually offering lower rates to locals. There is a company called Stand-by Golf that offers unsold tee times that may come in handy for you.
Several of the hotels are affiliated with local golf courses, and offer packages for guests. Harrah's Casino has a few courses that they work with. Mandalay Bay, MGM / Mirage and Wynn's Casino also offer golf packages with their affiliated courses.
