We are planning our first dvc vacation. One of our friends family is going with us and one other may join (either a group of eight or eleven). We are looking to go over the feb break next year and the availability seems to be getting worse as the seven month mark gets closer. We aren't sure whether the third family will join but the three bedroom availability seems worse than the two bedroom. Am I better off reserving a three bedroom and switching later if they don't join or is two bedroom harder to get closer to the time?
