The easiest way to get to Kael, by far, is to port to Wakening Lands - then have your porter immediately cast Lesser Succor. You will be evacked to the entrance to Kael! Furthermore, if you need to get to the EW side of Kael to join your party (or whatever other reasons) zone in to Kael with your porter, and cast succor again - you will be taken to the EW zone inside Kael.
Cheers!
