Ouch. Sorry to hear that it happened. Yes, it can be repaired through Nikon or an authorized repar facility.
Hope you are still able to enjoy your trip. (Post again, when you get back, in the Repair Forum and I can get you a list of authorized repair facilities and Nikon USA's info. Since the repair was not due to manufacturer defect, you will probably have to pay for the repair but if you bought the camera with a credit card, you may have some insurance or buyer's protection plan through your credit card company.)
