I do think being able to bypass that would come in handy many times. And as Piano Walrus said, the option to reopen closed instances would be great, or launch an instance closed to be able to prepare an event prior to the actual event start.

This would include being able to join YOUR OWN CREATED Invite instance.

I would also appreciate this, as I'm often unable to visit closed instances of worlds I've created despite many people still being in them. An option for me to reopen them would also be nice.
