Niagara Falls, Canada

Niagara Falls is a top destination with a split personality of sorts, picture a citizen of both the United States and Canada. Views are generally accepted to be better on the Canadian side, with more to do and Ontario's excellent wineries adjacent. A Fallsview room, where you can look out and see the falls, is a real plus--you may even be able to watch the fireworks over the falls from your room (fireworks are only on Fri and Sun nights in the summer) . Be careful, though--one hotel is said to have let trees grow tall enough to block the view from their lower "fallsview" rooms. Fallsview rooms command a premium; you may want to look out your room's windows promptly upon arrival, to make sure that the view meets your expectations. (Complaining the next day may not be quite as effective.)
To avoid the crowds on the Maid of the Mist or Journey Behind the Falls, arrive early in the morning when the attractions first open. You will be amazed at how quiet and empty things are.
