We are thinking of putting in our first ever exchange. It's for week 51 of 2016. The question I have is this. What if something happens between now and then we are not able to go during that week? We will have put in our money to exchange it, do we get that money back or do we forfeit it along with our TPU points? (we have a fixed week with RCI). Ir ealize we have already deposited our week, so I am not asking about getting that back, but is the exchange set in stone? Thanks.
