We just did this with some friends. We all shared one; just know only one person will see all the photos without the watermark so it was kinda annoying if people wanted to share pictures the same day. Often at night, I would download and text my friends so they could post online. At the end of the trip, I downloaded them all and shared with everyone to print or do what they wanted.
One thing I’d mention to everyone in your group, document what time people ride in case the photo doesn’t get linked properly. PhotoPass photographers were never an issue but a lot of our ride photos didn’t load, even after 24-48 hours. I kept track every day of the missing photos and called once we were home. A very nice cast member at PhotoPass found every single picture, but I often had a short window to have her search through.
