I have made a few ADRs that I now want to cancel as better options have become available for new years eve dinner (now get kano, jiko boma maya, grand floridian and california grill all of which were full when I tried to get them 90days out). I have now booked Kona but need to cancel the one I had at the WAVE. Can this be done online or do I have to phone from the UK. I also need to cancel San agels for Xmas day as we are now not going into a park that day.
