An excursion is an activity one might take during a vacation. Some companies cater to booking a-la-carte experiences and activities that are untethered to a complete package or hotel. Many times you will book cruise port shore excursions with the cruise itself, but oftentimes you can find a better rate below.
This a great site for tours, excursions, and activities of all kinds. The commission isn't great, but the ease of booking and amazing customer experience make up for it. [link]
