It'd be pointless for you to do that quest anyhow as you currently cannot use the inn in Ul'dah. They've been down for quite some time. My suggestion, don't waste your time on it now, and do it in gridania or LL, as theres really no need to do Ul'dah's. Perhaps thats the reason why you are unable to do the quest in the first place?? Cuz they are currently down....
