The towns around the park are small, and we've measured festival-Saturday availability dropping to about half of a normal weekend.When rooms open & cancellations appearBookings move at every lineup announcement and ticket lottery. Rooms come back around free-cancellation deadlines, and Takamatsu city on the JR line adds options.If it's full: nearby towns
