I thought about how this is going to work, and I think they are just going to have Snow, David, Emma, Belle, and Zelena stay in SB with their children (Neal, Gideon, Robin, and probably a CaptainSwan baby). Recently they said that Henry was going to contact his family for help, and that Regina, Killian, and Rumple are the ones who are going to go. Here is going to be the reasoning of everyone:

Regina: Henry is her adopted son, she is not going to not go and help him. Furthurmore, she has magic, which would be useful in a FTL. Finally, the only thing really keeping her in SB is that she is the mayor, and she can pass that duty to someone else easily enough.

Killian: Is going to go so Emma can stay in SB with the baby. Going to say how he has more experience in strange realms, and that he wants to make sure Emma and the baby stay safe, and also that Emma needs to make sure things stay safe in SB.

Rumple: Going to go because Henry is his grandson, and last direct tie to Baelfire, and because he wants to set a good example for Gideon. Also, he has magic, and knows alot about FTL's.

Emma: Is going to want to go, but Regina and Killian will convince her to stay and keep SB safe. Regina may even make Emma the mayor.

Snow: Is going to want to go, but Regina will convince her to stay and help Emma with things, and also take care of Neal.

David: Is going to want to go, but Killian will convince him to stay and help Emma with things, and also take care of Neal.

Belle: I don't think she is really going to want to go, even though she will want to help in some way, but Rumple will convince her she is more helpful staying in SB anyway, and taking care of Gideon.

Zelena: I don't think she is really going to want to go, and Regina will covince her that it is more important to stay in SB anyway, and take care of Robin.

See easy way to have these characters off the show, except for specific episodes flashbacks or present days.
