The locations are also used to show the route on a map. You can actually see it by clicking on a yellow location marker. It's a bit hidden because the UI is still a bit buggy, so until I get it fixed it's more of an easter egg. The "MVP" for collaborative albums would be sharing an account. At this point you could even create a new account just for the trip, so your friends don't get access to your other photos. I realize it's not ideal, but maybe it's enough to try it out? The albums are shared insofar as anyone with the link can see them and they get indexed by google. But there is no central feed where albums or photos might appear. Adding password protection and a noindex option on a per-album basis is also on my list.
