We were suddenly notified the day before that our Chinese-speaking tour was changed to an English-speaking tour. We hope that if there are any changes to the itinerary, we can be informed a bit earlier so we can evaluate alternative plans. Everyone was told to arrive at the meeting point half an hour early to wait for the bus, but the bus arrived later than the scheduled meeting time, and there was no proactive notification, which made the participants anxious. Other than that, everything else was quite good, and some of Iceland's scenery is truly magnificent and beautiful!
