so far i have seen many lvls use it ...a relative who is a lvl 20 or 30 something i forget goes out there ...although he cant do quest yet.... theres a few lvl 70s or so that go and can use the facilities....i myself ranged there from about range lv 60 to lv 80.,,and i still go out from time to time just to mess around and im lvl 88 range now.... i hope this is what you were asking....since im way new to forums
