I have made three point transfers this year and all of them went very smoothly. I was transfering to other owners that were renting from me. Key things to remember are:
1) Know exactly where your reciepient wants the points to go. Including what resort contract if they have multiples and what use year they should be applied to.
2) Remember that you can't give and recieve in the same use year. Don't transfer out if you think you might need to tranfer in later in the year...
That is about it, except of course for following up within a couple of days and making sure that everything went the way it was supposed to...
