We are going to Disney from Nov 28th till Dec 5th, it will be myself, DH and our 5yo daughter. We have a 19yo that does not want to go, he works two jobs and he will have finals when we get back. My concern is that he will change is mind a couple of weeks before the trip and want to go with us. We are doing the Free Dining, would this be a problem? The hotel sleeps four, so not having a vacancy is not an issue, but because it is past the Sept 26th date for Free Dining, would there be a problem adding him? Thanks!
