TL;DR
Buy bands when the interactive game is a real priority. Skip or buy fewer when your group mainly wants rides, photos, or a short land visit.
The decision
The band is not just merch. It changes how your group uses time in Super Nintendo World. That can be great if gameplay is the point.
Buy it when
Your kids care about interactive play, your group has time for repeat challenges, and you are comfortable letting the land become a game for a while.
Skip it when
You only have a short Epic day, your group is ride-first, or buying one for everyone turns into budget stress.
What I would do
For families, I would either buy one per kid who truly cares or one shared family band. I would not buy four just because the display is persuasive.
Use this quick checklist
- Decide if gameplay is a priority
- Choose who actually needs a band
- Set a time limit for challenges
- Keep ride priorities separate
- Treat scores as bonus
