In order to maintain the simplicity of the place and really appeal to those who need and appreciate such places, Desert Castle has not been built onto, and sets limits on the number of people who stay and which people are allowed to stay there. "Gatecrashers," who drop in without a reservation, are also not welcome.
為了致力於讓這裡更純粹，能真正屬於需要、欣賞這個空間的人，「沙漠風情」不但不擴充，甚至控制人數、篩選客人，也不接受沒有預約、臨時闖入的「不速之客」。
