Dear Druid, Thanks for organizing the conference 2024. I enjoy it very much. I thought the two excursions are in different days. However, I got to know that they are at the same time. I would like to join the excursion by boat. Could you please help me cancel the excursion on foot and give me a refund? Btw, when is the after party? I plan to add the after party on the system by myself. Thanks for your time and kind help. Best wishes, Chen Ye Sent from my iPhone
