Yes, you also have to want to be there, but once there, Sunriver is a world unto itself (and close to a lot of other great year-round stuff). The stats; 211 Lodge guestrooms and over 300 vacation homes and condos, over 44k square feet of indoor meeting space plus a seemingly infinite amount of outdoor space, an average of 300 sunny days a year (so yes, it is feasible in the winter that you can golf and ski on the same day), four (!) golf courses, fishing, kayaking and canoeing, a marina, horseback riding stables, 45 miles of bike trails, a private airport, a full-service Spa, and about a million team building ideas (the use of the word “million” is called poetic license).
And one other cool thing… due to the amazing lack of light pollution at the resort (yes, that is a thing), the resort is home to the independently operated Oregon Observatory… and those folks are happy to bring some of their telescopes to your night-time events and show your attendees what the stars really look like.
The gist of all of this… consider it. :)
