I'd try and pick some 14ers as far away as possible as you can from Denver. Hordes of people out looking to hike/scramble the 14ers can be really thick close to Denver. It's worse on a weekend too.
I remember one weekend going in to climb a route on Mount Meeker right next to Long's Peak. Meeker is not 14, but you need to use the same trail approach. Folks on the trail were a mile deep. trying to race and scoot around the slow masses was tricky. We got yelled at a couple times because we didn't say, "passing," on the trail. It's hard to say, "passing," 50,000 times.
