We just confirmed an exchange into Sheraton Vistana and would like advice on any requests we should make.We would like to have the newest units available, and we are checking in on a Sunday. Would we get better results calling or emailing? I did a search on this board and found one thread with a request form.Any other hints will be greatly appreciated! I did a lot of research all over the web and the best info is still here on the DIS!!!!
