What are the advantages of being a platinum member? From our travel agent in trying to book a new seven day cruise on the Allure it got us $1 off a balcony room. Are there advantages that were missing? Or should we start looking at other Cruise Lines why be loyal if we're not receiving any benefits? I'm just trying to find out what the advantages are or what we're missing out on. Can anybody please help and thank you
