We will be arriving in Buffalo around 12:30pm 5/29/17, will rent car and then head to the Canadian side (will spend 2-3 days there touring city/falls and doing a college visit for DS16). DH and I have seen the falls from Canada during winter, and after searching both forums it looks like the overwhelming consensus is that the Canadian side is better.
My question is whether or not the cave of the winds is worth spending a few hours in NY before heading over to Canada? Maybe in lieu of the behind the falls tour in Canada? If it's really not much difference, we can use the extra hours doing something different in Canada, but if it's a really unique experience, then I'm happy to spend the extra time in NY. Our kids are 8, 12, and 16; which of those experiences would be better for them (just your opinion, I know you can't speak for what my kids would like! )?
