It costs $200 per day (low season) and $250 per day (high season) to visit Bhutan (https://www.tourism.gov.bt/plan/faq ), bringing in over $120M per year (https://www.macrotrends.net/countries/BTN/bhutan/tourism-sta... ) from about 250,000 tourists (https://thebhutanese.bt/tourist-arrival-increased-by-13-till... ). The fee includes room and board.

I'll suspect more people have Venice on their bucket list than Bhutan, so that would be a minimum bound answer for your question.
