You can cancel after your 45 days, but there will be a charge to change the reservation. I had the QS plan booked, called after my 45 days to upgrade to the regular plan and they told me there was no charge when you are upgrading, just to downgrade. So if you are upgrading the DP, you will not be charged. If you are removing it without upgrading, I believe there will be a $50 charge, but don't quote me on that price, I just remember reading something to that effect. In all honesty, I wish I would have stayed with the QS plan and payed for my one TS OOP because I am now having trouble gaining the ADR's I want so close to arrival and when I worked it out on paper, taking into account that I will now have to purchase my mugs ( which we do use a lot), I will not be breaking even, I will be putting more money out. Just me and DH are going for a few days but when DS comes, the regular plan makes more sense because he likes to do some serious eating!
