There were 6 of us - my wife and me, my daughter, her husband and two sons - ages 7 & 9.
What do they like to do?
At this point, almost anything that gets them away from home.
Our son is an attorney (bankruptcy) so he can put in some long hours. DIL is happy when he can take a break and enjoy time with the family.
They are looking forward to a week I got them in Williamsburg next month. DIL's parents have a summer place on one of the lakes in Chautauqua County so the kids like being around water.
We spent a week at Carriage Ridge a few years back so we are familiar with the area. We did one of the cruises on Georgian Bay.
They do have free wifi at the resort and most of the time we had good connections, there were a couple of times that we lost it, but it came back up within a few minutes.
We went to Wasaga Beach and enjoyed the beach, but not the water - it was nasty looking. We did enjoy Georgian Bay Islands National Park and Bruce Peninsula National Park. We went to each one for day and it was a long day - pretty good drive, a lot of road construction, etc. The water was great, but cool in the National Parks.
The kids and grandkids went biking and hiking, a lot and had fun. They took their own bikes.
