A friend at work got a pin code in the mail for free dining from the end of april until august 13th.. I have a vaca. booked starting aug. 14th with a 35% discount on my rooms. Here are my questions: 1. Can I use my friends code or is it "person specific? 2. If I can which is a better discount..free dining (family of 5) or the 35% off the polynesian? My dates are sort of flexible. Thanks!!
