18. Based on the main idea, which would be the best title for the passage below? Galactic Suite, the first hotel planned in space, expects to open for business in 2012. It would allow guests to travel around the world in 80 minutes. Its Barcelona-based architects say the space hotel will be the most expensive in the galaxy, costing $4 million for a three-day stay. During that time, guests would see the sun rise 15 times a day. They would use Velcro suits to crawl around their pod rooms by sticking themselves to the walls like Spiderman. Company director Xavier Claramunt says the three-bedroom boutique hotel's joined up pod structure, which makes it look like a model of molecules, was dictated by the fact that each pod room had to fit inside a rocket to be taken into space. "It's the bathrooms in zero gravity that are the biggest challenge," says Claramunt. However, they may have solved the issue of how to take a shower in weightlessness. The guests will enter a spa room in which bubbles of water will float around. When guests are not admiring the view from their portholes, they will take part in scientific experiments on space travel. Galactic Suite began as a hobby for former aerospace engineer Claramunt, until a space enthusiast decided to make the science-fiction fantasy a reality by fronting most of the $3 billion needed to build the hotel.
