Fort Condor has a free INN. All you have to do is agree to help them. You don't even have to partake in any of the mini-game battles there, you just have to agree to (you lyin' sack of potatoes ). Fort Condor is that rock sticking out of the ground with a giant bird on top of it right outside of the Mythril Mines (the cave you came from the swamp with the snake, Midgar Zolom).
