Improve agency contracts, meet room requirements, increase visitor satisfaction, and unlock more advanced rooms as your hotel rises from zero stars.
HOW THE HOTEL WORKS
Choose your hotel location, place walls, and build rooms to shape how rooms are arranged. Each room you add increases the load on services and utilities, and unmet demand reduces room condition and visitor satisfaction.
Tourism agency contracts are the main way to bring in public visitors. Each contract sends a specific type and number of visitors. Completing agency missions improves those contracts and increases visitor flow. Private visitors arrive in their own ships through spaceports. Merchants and companions arrive through their own routes and add their own needs.
Visitors come from different origins and wealth classes. Earthborn, Lunite, Martian, and Spacer visitors each have their own needs, travel times, and expectations. Economy, Business, and First Class visitors require different standards. Each visitor tracks room, food, recreation, and special satisfaction. These combine into an overall rating. Primary traits such as Casual, Cultural, Foodie, and Thrill Seeker place more weight on specific satisfaction categories.
Room placement and desirability are central to the game. Nearby rooms, services, and modules change desirability, which affects whether visitors choose to use or rent those rooms. Recreation rooms and supporting facilities can increase desirability, while poor placement reduces it.
You also balance desirability with income. Increasing rent raises revenue but lowers desirability, making rooms harder to fill. Finding the right balance between pricing and demand is key to growth.
Services affect room condition and visitor experience. Cleaning maintains cleanliness, maintenance keeps rooms operational, security affects safety, and room service supports visitor needs. Construction allows you to expand and modify rooms.
Utilities supply the hotel. Energy, ventilation, communications, water, and shielding must match the size and demand of your rooms.
Crew operate the hotel in two alternating shifts. One shift is active while the other is away. You assign crew to roles to keep services, utilities, and daily operations running.
Organisations offer missions that provide rewards such as credits and unlocks. Completing missions expands your options and opens new ways to develop the hotel.
Your hotel begins at zero stars. To reach higher star ratings, you need to build the required rooms, increase room variety, and reach the overall visitor satisfaction needed for each level. Higher star ratings unlock more advanced rooms and allow you to serve more demanding visitors.
A CONNECTED HOTEL SIMULATION
Room placement affects desirability. Desirability affects visitor choice. Rents affect income and demand. Services affect room condition. Utilities support expansion. Missions, reviews, contracts, and star ratings shape how your hotel develops.
Growth works best when the whole hotel works together.
