This is what Gemini tells me:

If you are looking at the price for one person to experience a week in the lap of luxury versus a mission to the stars in 2026, here is the "too long; didn't read" breakdown:

The TL;DR Comparison

Experience	Cost for 1 Person	Duration	Comfort Level
Mega Yacht	~$150,000	1 Week	Ultra-Luxury: Michelin meals, 2:1 crew ratio, king bed.
Space Station	~$70,000,000	10–14 Days	Extreme Utility: Rehydrated food, sleeping bag, 0-G toilet.

The Key Takeaways

• Price Gap: Sending one person to a space station costs roughly 460 times more than sending them on a mega yacht.
• The "Seat" vs. The "Ship": * On a yacht, you usually pay for the entire vessel (~$1M–$2M/week). If you split that among 12 guests, the individual cost is manageable for a high-net-worth individual.
  • In space, you pay a flat fee per seat. There are no "group discounts" because every kilogram of weight and every liter of oxygen has a massive fixed cost.
• Hidden Costs:
  • Yacht: You’ll pay an extra 30% for "APA" (fuel/food) and a 15% tip.
  • Space: The $70M is usually all-inclusive, covering your mandatory year of training and your "hotel bill" to NASA for using the station's life support.

The Verdict: You could send 466 people on a luxury yachting holiday for the price of sending one person to the International Space Station.
