Since you are not subscribed to a store, you cannot use the Vacation feature that you might have seen in the past, with an orange banner running across the listing. If taking vacation, you will have to end your listings early, and ship the ones you have completed.
If you're feeling lucky, you could reset your handling time to match the number of days you will be absent and add a line of text to your Item Descriptions to say you will be away. It doesn't guarantee buyers will read or notice any of that, and you might still catch flack for taking too long to ship and/or rescind to messages,
