Now that Matt Ginella has revealed his Top 10 buddies trip golf destinations, I'd like to chime in with a couple destinations left off his list that also deserve some consideration from your group (especially if you're on the west coast):
Central Oregon: Bandon's shadow in the Pacific Northwest has grown so large that golf groups may forget about its high desert neighbor to the east.
This is the destination for the group that like more than just golf and craft beer but all things under the sun: fishing, hiking, mountain biking are all in abundance. In fact, at certain times of year you can ski at Mt. Bachelor and play golf in the same day. Or, on a balmy summer day, you can tube the Deschutes River in the heart of town.
But if you'd rather just play 36 holes a day, the golf in central Oregon is phenomenal. Pronghorn and Brasada Canyons (two of my favorite courses in the U.S.), plus Crosswater at Sunriver and Tetherow anchor the high-end stuff and each is entirely different from the other. The destination is also versatile for a lot of budgets. Middle-tier golf in the $50-75 range is really good: Aspen Lakes, Eagle Crest Resort, Widgi Creek and Black Butte Ranch.
Now, the nightlife in Bend isn't wild (well, maybe compared to sleepy Bandon it is), but there's a great craft beer scene and some unique bars. Pronghorn and Brasada Ranch have embraced the luxury, multi-room furnished condo concept where your whole group can stay under one roof, stock up the fridge and smoke cigars around a bonfire on a cool evening.
Lake Tahoe (and Reno): This was a serious contender for my own bachelor party coming up in September (before we eventually opted for Scottsdale). The golf throughout the High Sierra is fantastic. But the easiest stay-and-play option for nightlife is on Lake Tahoe's South Shore at one of the big casino hotels like Harrah's, Harveys and Montbleu, and golf at one of the great, classic resort courses in the world: Edgewood Tahoe. Now, I'd be totally okay with playing Edgewood Tahoe all weekend, but it's also $200-plus for 18 holes per man, so to save some money you could hop over the pass to Genoa Lakes for more affordable golf in Carson Valley. Or, you can drive up to the North Shore (everyone who goes to Tahoe needs to drive its circumference, stop off at Emerald Bay and play the wonderful Robert Trent Jones Sr. Championship Course at Incline Village.
If you want the best collection of courses and nightlife in the area, do this: 24-hour nightlife plus the best golf, stay in Reno and during the day, make the 35-minute drive each day to the golf courses in Truckee: Gray's Crossing, Schaffer's Mill, Coyote Moon and Old Greenwood are all stellar, pure mountain golf picks. The public golf in Reno is pretty good (Red Hawk and Somersett are my favorites) but Truckee is world class. The premium you pay for golf in the mountains you'll save on bargain lodging at one of many Reno casino hotels.
