If I am in line and I need to go to the bathroom can I come back to my place in line

yes you can get back in line where we're at when u left to go the restroom

Never heard of them letting you back in line unless your party is in line.

If you're not alone you can get back with your party. If you have no one that can stay in line for you just let one of staff members know they let us back in line where we were. Or if we got to the side waiting on family members to come back from bathroom they let us on through when they got back. They were all really great about it.

The banshee ride has a bathroom pass about halfway through. So yes!
