But Gary had another idea. Imagine underground caverns with waterfalls one mile high. From giant sand dunes to giant volcanoes, Mars makes features of Earth pale by comparison. In 2130, humans will have permanently inhabited the planet for 80 years. Luxurious hotels replace the habitats of the early settlers.
Tourist attractions are pristine and protected.
A popular trend on Earth will be to take a one-year sabbatical and travel to Mars aboard a luxurious transport ship with artificial gravity decks. Available for your enjoyment would be low gravity sleeping quarters, low gravity showers, low gravity sports games, telescope observation decks, meals that taste better because of the uniform mixing of juices and heat concentration due to the lack of gravity. Balloons rides and Mars buggies allow patrons to do a little prospecting on their own or just enjoy the dunes and scenery. Having the same landmass as Earth, there will be plenty of new hideaways to discover.
