Since you don't have a Store, you can't use the Vacation Alert option.
Instead, close all your listings. They will go to your Unsold Items for the next 90 days.
When you get back from vacation, or the day before, use RELIST to open all of them again. You will be charged for the relists.
Your 71 listings will cost you between $3.50 and $21.00 to relist.
If you use the Sell Similar button instead you will probably not pay the fees for the first 50. But remember that manually doing this takes longer and your time is worth money too.
