If you don't have a higher level character or friend to help fly you around you can always do what I do for 5 of the same class and missing a healer / tank (mainly hunters).

Join LFD with 3 dps, once inside pull everything in sight, as you want to die. Once dead and released, res at spirit healer, now you have 3 characters ready to summon your other 2.

You now need to jump inside the instance and go AFK for 10 minutes while the debuff fades go smoke get a drink.
