Budget Backpacking Route Planner

I have [X weeks] and roughly $[budget] to backpack through [region/countries]. I want to prioritize [priorities: e.g. cheap food, hostels with community, nature over cities]. Suggest a route that: - Minimizes backtracking and expensive long-haul transport - Flags the 2-3 places worth spending extra days in vs. the ones to breeze through - Gives a rough daily budget breakdown (accommodation / food / transport / activities) - Calls out any visa, seasonal weather, or safety considerations I should check
