Cant speak for Kane himself but you see these guys travel hundreds of miles for a haircut, or pay for their barber to come to them, pay their chefs to basically live in etc etc.
Kane has his brother as his agent for crying out loud. If he wants to have his extended family and friends around him i have no doubt he will make it happen without issue.
I think we can be fairly sure that the Kane family won't be spending time searching for cheap flights or deciding that August is too expensive to visit, so they'll book to go later on in the year.
