Niagara Falls, Canada
Excellent tour. The bus was half an hour late, but the tour itself was fantastic. The guide Bob was funny and helpful. One of the best tours I've been on.
New York City, New York
This is a good tour if you are not at all familiar with New York, don't want to do any planning yourself and don't have a lot of time in town. Otherwise, it can be a tedious long day. The lunch was most unimpressive, but I was prepared for that based on previous reviews. The tour guide was foreign and (I'm afraid) quite boring. I know that I was in the US and there's a tipping culture, but I found the repeated hints and reminders rather annoying.
The beautiful country was practically ruined by this awful tour. There ought to be a big warning that the coach used is an outdated model with NO FUNCTIONING AIR CONDITIONING in the middle of summer. Issue raised with Viator customer service completely ignored. Very disappointed.
