I'm just playing around with this
Here we would describe this specific expedition - mostly short, with a link to more details if necessary. Maybe a photo, or embeded rotating photo gallery from this particular expedition.
Then dates and other details for the next expedition(if they are known)
Below this, the idea was to have just the instructors for this program (not all of them), but I don't know how to automatically filter.
Below this, four buttons that look similar for all programs, but go to different places. These are the four buttons we need, but these don't look great yet.
