OK - it is actually travelling for free and isn't even my idea - but I heard it in RC - tried it out and it works great!
Open your guild Roster and pick someone in your zone and click on them or a far off zone - then <Travel to player>
This will take you to the wayshrine closest to them. Now this may or may not be the wayshrine where you wish to go.
This doesn't matter since you are now at a wayshrine and can use it to go to the one you really want.
Free travel - in just a few steps.
Safe journ all!
