Toronto to East Cost Road trip Advice
 

Hi all, we r planning a road trip/Car Camping from Toronto to East Cost from mid of July to End 2016 for 18 Days.

Day 10: Toronto to Quebec City (2nights Stay)
Day 11: Quebec City sight Seeing.
Day 12: Quebec City to Fundy National Park (2 night Stay)
Day 13: Fundy camping and Sight seeing.
Day 14: Fundy to Saint John and Saint John to Digby (Ferry) --- Halifax (2 Nights Stay)
Day 15 : Halifax and near by places sight Seeing
Day 16: Cape Breton (2 Nights)
Day 17: Trials and activities in Cape Breton.
Day 18: Cape Breton to Wood Island (PEI) to Red Point (1 Night Stay)
Day 19: Red Point to Cavendish (1 Night)
Day 20: Cavendish to West Point ( 1 Night)
Day 21: West Point to Kouchibouguac National Park (2 Night)
Day 22: Activities at Kouchibouguac National Park
Day 23: Kouchibouguac National Park to Quebec/? (1 Night)
Day 24: Quebec/? to Toronto

So this the plan so far and this comes up to 15 Days.
My Question is.

1. Is this plan too aggressive for a family with 2 Kids?
2. We have 3 days more base on 18 days which we planned initially. (any more places that we can include in this trip).
3. While returning back can you suggest for any other place other than Quebec City that you can suggest as we would have already spend 2 days on this city during the onward travel.

Thank
