I recently discovered the charm of boat tours myself, and let me tell you, they're a fantastic way to explore a city! The Singapore River tour you mentioned sounds absolutely amazing. I can imagine sitting back and enjoying the beautiful sights along the river, especially during a night cruise with all those mesmerizing lights. Having a guide on board is a bonus, too, as they can provide interesting insights into the history and attractions. Speaking of tours, I recently stumbled upon some fascinating options for my next trip to Chicago. Here's the link I discovered https://www.getyourguide.com/chicago-l225/cruises-boat-tours-tc48/. It looks like they offer a variety of tours and experiences that are sure to make my visit even more memorable. I can't wait to hop on a boat or try something unique in the city!
