We're thinking of going to Niagra Falls for our vacation this year. It's within driving distance, and we've always wanted to go. We'll probably visit Canada while we're up there, but no details are planned yet. We're thinking July or August, so Sadie will be 17/18mo.

So, to anyone who's been or lives close: Advice/tips? Anything I should know or consider while planning? Must sees? Anything to avoid?
