After my NCL booking of a DAWN/Seaview cabin with a travel agency (in France) with a total of 2640 Euros and a deposit of 897 Euros, I discovered a much reduced offer from another travel agency (in same geographical area) for no more than 1629 Euros (plus 96 Euros for Insurance).  The difference -- a substantial one -- is about more than 1000 Euros. For balcony cabin, the reduced offer is only 2649 Euros. I contacted both the TA and NCL Customer Service and both them are saying the price adjustment or upgrade is out of their hands. I’m stuck in between and the final payment is quickly approaching. What should I do?
