A one-on-one planning session with a naturalist who lives in Yosemite: dates, group, and constraints turned into a plan that fits the park as it will actually be that week. Thirty minutes by call, or the same session asynchronously as a written plan. A few slots a month; when they are gone, they are gone.
Most planning questions are answered free in the Planning Guide, the itineraries, and the trip planner map; the consult is for plans with real constraints.
