We are going to be driving on a Saturday morning from Bar Harbor to Saint John, NB to (hopefully) catch the noon ferry over to Nova Scotia. Most map apps say its a 4.5 hour drive. Does that take into account the time change after you cross the border? I'm really nervous that we're not going to make the ferry! What time should we plan to leave Bar Harbor in order to get to Saint John by 11 or so (taking into account the time change)? Also, how long does it usually take to get through the border crossing at Calais?
