Area where you can level up very quickly!
Before you eagerly read this, please note that you can only do this on Disk 2. Also, the only time on Disc 2 that you can do this is on the area where you found Edea's orphanage, and you are fighting against the floating ship of Galbadia. There is an area that I found where if you fight the monsters, you can easily get from 600 experience to 700 experience after every battle. Using this method of training, I leveled up all my characters by 20 levels.
Alright, first walk into the main area of the ship, and save your game. Now walk into the hallway on the left, and then walk into the doorway on the left. You should now be in a giant room where a ice hockey stadium is. Run on the ice field until you encounter some monsters that look like hockey players. Use Ifrit and quickly kill them. Now after the battle you should get a lot of experience, and alot of AP points for your GF as well. All you have to do is keep repeating the step over and over until you get your party to the level that you want them to be on.
The best thing about this is that you are guaranteed to get over 500 experience points after each battle. Every battle you will see the enemy arrive in groups of either 3, or 4. So after every two battles, you should have had all your characters in your party grow a level. Maybe two. Your GFs will also grow levels, and get either 9 or 12 AP points every battle.
