Each chalet has its own Availability Calendar. If you position your cursor over the availability tab it should bring up a tab for each chalet. I make every effort to keep these up to date. As I am sure you can appreciate, there is often a time lag between people asking to book certain days and actually paying a deposit. I usually take people on trust i.e. if you request certain days I will usually reserve them for you until a deposit is paid.
Short breaks usually run from Mon-Thu or Fri-Sun (thats nights inclusive). Weekly breaks tend to be Fri-Thu. These days are not set in stone. If you require different days just email me.
