Thanks to anon for the following.
Recently we reported on an interview with Kristin Nairn (Hodor) saying he won't be in Game of Thrones season 5. Despite that, Isaac Hempstead-Wright (Bran) said he will appear in Season 5.
The video below is an interview with Isaac Hempstead-Wright promoting a movie (The Boxtrolls). At the end of the video (skip to 5:50), when asked what he's going to do next he answers the next season of Game of Thrones (and school).
So, it appears that when Kristin Nairn said "We have a season off", that "we" doesn't include Isaac Hempstead-Wright.
