Most childhood experiences are just part and parcel of the environment they live in. Does anyone think a child growing up in a rural area is missing out because they haven’t taken the tube through central London?!
Ah, see I grew up rurally, but urban skills are very easy to acquire, and rural kids almost entirely get opportunities to encounter them. (Of course, you get all sorts like people who are still worried about the tube as adults, and urban and rural dwellers who think a motorway is scary etc).
But on the whole, I've found that urben dwellers don't have the same understanding of the country as rural dwellers, and the majority of them NEVER acquire it.
But as this very thread shows, people can be fantastically touchy about being considered deprived of experiences.
I have experience of rural and urban environments. I have experience of five star hotels, international travel and camping in Wales. I have never been skiing, to South America, to India or any part of Southern Africa.
More experiences make people more broad minded and gives them a better cultural capital to draw on, but there's no need to be touchy about admitting that you haven't experienced something or provided it for your children. I'm sure they'll be just fine.
