<p>Some thoughts:</p>
<p>Altitude sickness: It’s not just the old folks. Some people just don’t process oxygen very well at altitude, and it’s no laughing matter. Some people just get sick. Others die. It’s rare, but it happens. If you think anyone in your family might have a problem, then take that into account when looking into the high mountains around most of the ski resorts.</p>
<p>There are a few questions I think you should ask yourself:</p>
<ol>
<li><p>How big will the reunion be? Will everyone just hang out and talk, or will you be scheduling activities? Will the activities be diverse for various interests and ages?</p></li>
<li><p>If you’re not going to do much except sit around and talk, anything will do and it will come down, essentially, to price. Some of the places being suggested here require one to take small planes from the Denver airport (if flying). Some of the ski resorts are cheap to get into because the fares are subsidized by the resorts. Others are very expensive.</p></li>
<li><p>Here are some suggestions based on what you might liike to do:</p></li>
</ol>
<p>Estes Park: Gateway to Rocky Mountain National Park and close enough to horseback riding, river rafting, rock climbing, and major metro areas to satisfy just about everyone. The Stanley Hotel is THE place to be if it’s affordable for you. Otherwise, there are many smaller hotels, though some are a bit primitive. If your family is into camping, this would be the place. It’s pretty high up, but not in the 9,000 foot range.</p>
<p>Boulder: All the outdoor activities you can imagine, but closer to good food, bars, splendid hiking trails, great shopping, and the like. If it’s summer, there are a number of cultural activities going on such as the Colorado Music Festival, Colorado Shakespeare Festival, etc.</p>
<p>Denver: Metro area. Close enough to outdoor activities but obviously more of the metro pleasures than Estes Park.</p>
<p>Colorado Springs: Close to Pike’s Peak, Garden of the Gods, some caverns, and several other attractions. I don’t find the town itself all that appealing, but the setting is breathtaking. It’s not as breathtaking as Estes Park, but it’s still quite lovely.</p>
<p>The ski resorts: All have much to offer, including off-season rates, golf, and other outdoor activities. Many have good shopping, though it’s often very overpriced.</p>
<p>Basically, if many from your family want the comforts of a metro area, then the Front Range (the east side of the mountains with Denver, C. Springs, Estes Park, and Boulder) are your best bet for both the outdoorsy types and the metro types. I’d say that Boulder probably offers the best mix, with Estes Park a bit more toward the rustic side and Denver and the Springs more towards the metro side. If you want to get away from it all, then Estes Park will certainly do, but western Colorado is far more remote.</p>
<p>Have fun.</p>
