We will have a family vacation in June 2018. We are 4 adults and 3 kids (ages 17, 14, 10).
I've been to most of the places mentioned in the itinerary with friends 2 years ago. I just want to show my family these places since I enjoyed them the first time. But one of the kids is a special child and is afraid of heights. So in this case, I will accompany him and just wait for the rest in a coffee shop or restaurant since I have already seen these places.

We want a relaxed vacation, so I just put in 2-3 places per day.

Please make any comments and/or suggestions on my prepared itinerary:

Day 1
Grouse Mountain
Capilano Bridge
Vancouver city tour

Day 2
Whistler

Day 3
Vancouver City (pls suggest)

Day 4
Victoria (Butchart Gardens)
