This is Muhammad Nagah - a fellow freelance Arabic translator on Fiverr since 2013. During this period, I had to go on and off vacation mode for over 12 times for my medical exams.
This is what you should do:
(1) Turn your “out of office” mode on, and set it to be 4 weeks. If you plan to go back in just 2 weeks, you can turn the vacation mode off once you are back without the need to wait for additional 2 weeks. The reason I recommend 4 weeks instead of only 2 weeks is for emergencies (for example, you decide to extend your vacation).
(2) Make sure you go “out of office” at least 5 days before the start of your vacation, and also to deliver all your active orders at least 5 days before the start date as well. This is to ensure you will be there to respond to your buyer’s revisions, if any.
The “out of office” mode will take your gigs off the search results. New buyers won’t be able to send you messages, and old buyers won’t be able to place orders. Everything will return back to normal once you are back from your vacation.
I hope this was helpful
