Each trip is carefully planned in detail, and you can read about the daily activities in the 'Itinerary' section of each trip page.
On many of our trips, the pace is usually pretty fast, so adding extra stops, especially those far from the planned route, is not usually possible.
However, for some itineraries where accommodation does not change, you can propose additional activities (e.g. a museum, theatre show, match, etc.) as long as they fit with the travel schedule and the whole group, including the Travel Coordinator, agrees to include them.
You can discuss this in the WhatsApp group created by the coordinator approximately 2 weeks before departure, or even while travelling.
