Acclimatization strategy belongs on a Cusco shortlist because altitude is the first planning decision, not an afterthought.
RouteVerdict planning edge: Build a slower first day and consider Sacred Valley pacing if altitude worries you.
Best execution: Arrival day.
Common mistake to avoid: Landing and immediately forcing a packed walking tour.
Acclimatization strategy is worth prioritizing when it matches your season, budget, and trip style.
Book the scarce or high-friction part first, then keep lower-stakes meals, walks, beaches, viewpoints, and recovery time flexible.
