Start with the room split rather than the maximum guest count. Agree on who needs a private room, who can share a bed and who is comfortable in bunks. The Sunkiss has four king bedrooms plus a bunk room with two full-over-full bunks. The Scottsdale Social has two king bedrooms, a room with two queens, another king bedroom and a room with two full-over-full bunks. Both homes have five bedrooms; a group of 10 or more should review the full sleeping layout before booking.
For a Sunday game, arriving Friday can give the group time to settle in and keep Saturday flexible. Treat that as a general planning approach, not a suggestion that either home is available for a particular weekend. Confirm check-in, check-out and every night of your stay on the home’s own website before arranging travel.
If you plan to tailgate, check the official rules for your parking area and agree on a meeting point with the group. Work backward from the latest kickoff time, allowing for parking, security and finding your seats without relying on a fixed travel-time estimate. Keep ticket access and a return plan clear for anyone arriving separately.
Check the official State Farm Stadium site for its current bag policy, permitted items, parking and entry guidance. Recheck the Cardinals schedule before departure and on game day. Stadium policies and kickoff changes are controlled by the venue and league, not by Trailstead Stays.
