Pretty much what Vyrena said. If I may add, I suggest spamming 1-5 first 3 nodes with DD/CL before your HQ level hits 80. Craft some Sonar+Depth Charge to fill each ship and you're good to go. You can opt for 4 ships leveling to control who gets MVP or go for 6 ships where you can mix in CAs to leech XP without them doing anything. Since this method is level-limited, the earlier you do it the more DD/CL/XX you can Kai Ni before you have to move on to other leveling spots. Ooi/Kitakami/Sendai aside, pick at least 4 DD and 3 CL to powerlevel to be on the safe side, and make sure they're high performers with good stats. The last time I did it, it took me 2 and a half days to grind a ship to 70 and 5~6 others to around 50/60.

Oh, and do craft planes for your daily. You'll probably need around 9 Reppuu for some of the crazier maps.
