You can only do a vacation hold if you have an ebay store. You'll have to either end your listings and relist when you get back or have a family member or friend handle your listings for you.
______________________________________________________________ OP's - give details and don't make us guess what you're asking use complete sentences and paragraphs (easier to read) don't type in all caps (hard to read)
RESPONDER's - be polite and not berating or condescending or sarcastic don't correct the OP's spelling, etc. - that's not what we're here for don't type in large fonts - just as bad as OP typing in caps
