My cruise departs at the end of this month and I noticed that the cruise price has dropped since when I originally booked. Same room category and everything. About $400 total difference. I booked through Expedia and contacted them about a possible price adjustment and they said they couldn’t do anything since the final payment due date has passed? Which confused me since, I paid it fully when I first booked it. Anyways, I tried to push it harder and they ended up bringing a NCL rep on the line and they said they couldn’t do anything for me besides put in a “ticket request”. Does anyone have any tips or tricks?
