                  We value the enthusiasm of travelers who want to share their favorite places with
                  the NomadMania community. Every suggestion reflects passion for exploration, and
                  we appreciate the time and thought that goes into each contribution to the series.
                  {'\n\n'}At the same time, not all submissions will be added to the map. We have a
                  dedicated team that is tasked to review all suggestions and maintain an overall
                  balance across regions and topics and to prevent overcrowding in certain areas.
                  {'\n\n'}For this reason, even good suggestions may occasionally be declined. We
                  hope you understand this approach, and we thank you for helping us shape a map
                  that highlights the richness of travel across the world.{'\n\n'}Best regards, the
