I went back and edited mine. I decided not to make a change and when I updated it I thought it had lost all my excursion as it said "no excursions booked" However in reality all the previous excursions were still there.
I believe it just shows the "changes" when you open it up again was ONLY on the update showing no NEW excursions were booked and that message relates ONLY to the update. Is that as clear as mud?
