When my husband traveled for work, he'd go all over the US. He said New York, LA, and San Francisco were three of the dirtiest and most overpriced places he's ever been. Still, New York has decent public transportation options, fantastic food, and tons of activities to participate in. San Francisco also has wonderful food, especially if you like sea food. There are a lot of parks, shopping, and you can ride the cable line. But LA was just a letdown altogether.
I wish UK-based YouTubers made more of an effort researching travel destinations in North America. For instance, Toronto is not the only city in Canada worth visiting. Just like California, New York, and Florida aren't the only three states in the US. If they really thought about what they wanted out of traveling, they'd be surprised what they could find.
My husband and I plan on taking our girls whale watching this year in Nova Scotia. For summer holidays we're going to a cousin's wedding in Montana and I doubt will spend much time indoors at all. We've asked the girls what they'd like to do and we've already got a list longer than our arms. But that's the exciting part of traveling.
