How complex is the Tours section?
https://codex.buddypress.org/plugin-development/creating-a-custom-buddypress-component/
though the BuddyPress Skeleton Component needs to be updated
It’s similar to the blog section. The user will input information for the tour(description, title, pictures, and videos) and the readers can comment on the tour.
I’ll take a look through the skeleton component. Will I actually be able to build a new page with this though?
There are different approaches to what you want to do which includes deciding whether you will allow your users to post from the backend or to post always from the front end. My approach would be to use EventPress plugin https://wordpress.org/extend/plugins/eventpress/ along with with http://buddydev.com/plugins/eventpress-gallery/ which requires the premium BP Gallery plugin http://buddydev.com/plugins/bp-gallery/ which has images, audio, video galleries. Perhaps others would like to share what their approaches would be.
I’d build it as a custom post type
