We are a family of 4 travelling from Toronto to NB in August. We plan to make it to Riviere du Loup on day 1 (12hrs I am hoping, hotel booked) and then the next night we are booked at Hopewell rocks. We would like to spend a few hours at Kelly's beach on the way to Hopewell. Is this reasonable? How much time are we adding to our drive by going across the north part of NB to get to Kelly's beach and then south to Hopewell cape? Just want to be realistic when travelling with kids. Thanks in advance for any input!
