You can walk very easily to Hard Rock. You can also take the boat from City Walk to Hard Rock and to Portofino. Its a nice ride on the boat. We've also been lucky enough to have the staff at HRH take us over to Portofino in a limo (when its just been sitting around waiting for someone at HRH); we've just tipped them for their service. If you see a limo hanging around the lobby - just ask, you may be surprised.
