Hmmmmm. Next year's calendar is kind of tricky. If the marathon is the weekend of the 10th-13th, the next weekend is the Martin Luther King, Jr. holiday weekend, and the Saturday/Sunday of MLK weekend hits 8's and 9's on the Touring Plans crowd calendar.
But if we waited until the crowds subside again and do the 24th-28th, that would probably count out our runners. Crowd levels really aren't bad during Marathon Weekend itself. The only question is whether our runners would end up excluded from too much of our activites, because they're on a training schedule and/or recovering from running.
