I recently bought 6 tickets to hike Mt. St. Helens in June, I inadvertently choose the wrong date by one day. I am having NO sucess in getting someone to help me change my tickets -- I realized my mistake within minutes of my booking, however it seems to be unfixable, and our group cannot hike the day the tickets are for related to work schedules.
Has anyone else had experience with this, or know about selling purchased tickets to other people, or have any advice, other than paying attention in the first place
