Clifton Hill Niagara Falls

I drive a school bus and EVERY time I come here an older lady at the wicket she gives us a hard time about parking that has been paid in advance. No other person there has a problem with it just her and it’s everytime. Today we had to wait 15 mins in a hot bus while she called and radioed and called and radioed. Our staff had proof they paid and she still was nasty Being a tourist area customer service should be a priority
