Should I rent a stroller???

Yes, your son may have said it, but often they get their "opinions" unintentionally from their role models.

Thank you, that is exactly what I wanted to say but couldn't figure out how to say it tactfully.

What works for you is great, but please don't call other families ridiculous or lazy because they choose to navigate the park different from your family.
