Whenever you take time off, you can set your listings to inactive until you are ready to fulfill orders again.
This prevents customers from placing orders that might not be fulfilled right away. Not only is this the right customer experience, it can also help you relax and enjoy your time off.
When you are ready to sell again, just set your listings back to active. Within an hour your listings will again be available for sale on Amazon.com.

Happy selling (and resting up) as the year comes to a close!
