EF could be the destination, because in most of the examples above the portal was opened from the Enchanted Forest and therefore most likely with a destination in mind. Henry/Greg/Tamara's portal may have been intended to take them to Neverland, so it may  be that if a bean is thrown/activated without a specific location in mind they automatically default to the Enchanted Forest.

Bae's was intentional, he wanted to leave to go to a place without magic. Hook chose to leave the EF and wanted to go to Neverland, so therefore that was his destination. Same with the others. Hook and Cora wanted to find their way to Storybrook.
