1. Trade with Señor Gaudini: He'll exchange 5 universal blueprints for 1 Special Super Hotel blueprint once every 6 hours.

2. Collect profits from basic hotels: When collecting profits, there's always a chance to get a Special Super Hotel blueprint (maximum 30 per week).

3. Purchase blueprints with crystals.

4. Host third events in Standard Super Hotels: When hosting events, there's always a chance to get a Special Super Hotel blueprint (maximum 5 per week).

5. Host third events in Elite Super Hotels: When hosting events, there's always a chance to get a Special Super Hotel blueprint (maximum 15 per week).

Remember: the more Super Hotels you have, the higher your chances of getting blueprints when hosting events in them. Event duration is also important: the longer it lasts, the higher your chances of success. This way, you can collect blueprints faster, but not exceeding the weekly limit.
