I'm going to rewatch all the episodes, one a week. So 67 weeks from now is roughly Christmas/New Years 2018 and possibly when the final season could be out and if it is early 2019, I won't be too far off.
Anyway, after watching the beginning of the very first episode today, we see Jaime and Cersei talking in Kings Landing, 1 min later Kat telling Ned that the King is heading to Winterfell, and then 2 min later, all the Baratheons and Lannisters are in Winterfell. So even though we all complained about how fast everyone travel this past season, it wasn't like it wasn't done before (just not to the extent it happen this past season).
