Having resting bonus available helps a lot so always log out in a sanctuary (you can tell it's accumulating if you see the crescent moon icon to the right of the experience bar).
Side note on the Chocobo. Having the bird out actually cuts your earned XP per kill in half (that other half is given to the Chocobo to level them up) - but it makes up for it by increasing your potential kills-per-minute and by lowering the time you individually spend per target.

Only thing that sucks is that you can't use the DF while the Chocobo is up - because it considers you to already be in a party.

I wish they'd fix that.
