The Parking Lot Planet

We give conditions for an exoplanetary system to function as an idealamusement park/vacation resort (with its separate parking lot, of course); incase of massive human interplanetary colonization. Our considerations stem fromthe fact that an amusement park needs a parking lot of roughly the same surfacearea, thus the best option for its construction would be a system with at least2 planets close to each other for easy tourist transportation. We also discussthe likelihood of finding such a system out there to cut down on constructioncosts.
