If you stick to the more conventional camps, Kuftal Tunnel is the start of a loooong line of crabs for you to kill. While most people won't even think of xp'ing without a Red Mage or a Bard for the mana Refresh, those two jobs are even more important here because the Robber Crabs love to spam buffs on themselves, not to mention that they also like using Bubble Shower (AoE STR-Down) to keep White Mages happy, too.
The passageway that spans (I-4) through to (I-7) is quite literally infested with Robber Crabs for you to xp on, so while pulls might be long if the place is crowded, it's unlikely you'll actually run out of mobs. The Cape Terrigan zone camp can even support two parties if camps are all taken, although it is a rather tight squeeze in there.
One thing to be very careful of if you're not camping at the Cape Terrigan zone, is Guivre that occasionally pops around to make life interesting. Guivre will make mincemeat of you and your party, so if you see him, put up both Sneak and Invisible and /shout to warn the zone know that he is around. Having a wyvern run rampage across the xp parties might look funny, but he really does disrupt things, especially since he wanders all over the top floor of Kuftal, too. I hear he despawns eventually, if left alone, although I have no idea how long it takes for him to do so.
