For many years it has been nearly impossible. We would usually have multiple family/friends try and login a whole year ahead of time, at 8am etc. Sometimes we get it, usually we don't. Last year we got lucky and were able to get a few of them, but they changed things so that only one person can log in at a time per timeshare.
What are people's experiences with this? What is your success rate? My friend made software that reserves it for him automatically, even for peak week. He offered for me to use it but I'm concerned it violates TOS (does anyone know if it explicitly does??), but apparently it works. I dunno at this point I'm thinking of selling the timeshares. I have been getting a different week, renting it out, and that covers the maintenance cost, but really I'd like to go during Christmas, or at least be able to rent it out Christmas week and get back some of my investment.
EDIT: to be clear, this is for platinum
