Pole Creek is great golf course in the Tabernash area. 27 holes, incredible views.
My area is 40 min or so from an entrance to RMNP. If you go through Boulder to RMNP, you can take Trail Ridge Road and that will give you amazing views. Mid July there is a Jazz Fest in WP. Brings in a pretty good crowd but I don't think it is anything to write home about. A great 3 hour hike on my property isn't too strenuous and gets you a good taste of the mountains. 7ish hour hike to the Devil's Thumb is fairly strenuous but will put you right on the continental divide. Grand Lake will be about 80 degrees and sunny with no humidity. Maybe worth renting a boat. Chicat and ChicatGF would be willing to join you on any of these activities. Even if you just go through Denver for a day we will join you for a meal.
