We used this for a corporate retreat to keep everyone informed and work out the logistics of travel & topics of what we'd cover each day (using the schedule). I know that there were more tools to choose from, but we decided on Chat, Schedule, and Checklist. The group of about 30 of us enjoyed Guestboard because it was a great middle ground between a giant group email and more expensive planning solutions that have a large learning curve. Customer service was extremely responsive when we had a question about permission roles, and while everyone was generally expecting them, the invitations were clean and visually appealing. It's a very adaptable tool, and I can see it being used for a wide variety of events.

The thing I liked best was the modular functions that it provides. They were easy to activate and allowed me to customize my event to my needs. The most helpful features were: the message board/chat to connect with everyone, the ability to book our groups' Airbnb through the platform, and the shared resource center to share pertinent information. Lastly, the UX design and color scheme are sleek and elegant so you can use this for your bachelor party or even your wedding.
