Do they offer a free shuttle for guests to shopping/dining areas? Are there onsite activities (paddle boarding, kayaking, etc) and do they cost extra? Thanks!

No. They stopped offering the free shuttles as of January 2024

Yes!

Yes, they do have a free shuttle, we only used it once to another restaurant at a nearby hotel. I am not sure how far they will travel. We had a rental car so we mostly drove ourselves.
