Tavelocity, Yahoo and Orbitz will refund you the difference or get you an upgrade if avaliable. Any good TA will do this for you however they rarley will do it on there own and watch the prices for you, you need to sit a computer do your research and be prepared to be on hold forever. I will tell you that from personal experience recently because the price of my upcoming cruise dropped 1% I was able to go from a 7A to a 8C with a much larger room and balcony and recieved a $230.00 credit to my credit card. Sounds easy...NOT easy I had to call at least 6 times and my persistance paid off. Good luck to all!!
