How a visit works

Questions parents ask

Still wondering? Call (866) 306-1384 and talk to a person.

How can the character greet a shy child?

Begin with a little space and a wave. Let the child approach, remain with a caregiver or watch without joining.

How do we keep guest participation manageable?

Choose one short group activity and have an adult invite guests in. Make taking part optional, including for photos.

What needs confirmation before party day?

Ask us about the requested date, program details and cost. Separately confirm the location's permission and weather plan with its operator.

Character parties in Onset

A character visit in Onset can have a simple rhythm: a friendly hello, a special moment for the birthday child, then a short activity for guests who want to join. Keep a nearby adult available and let children choose a wave, photo or quiet observation. For an outdoor plan, name one person to watch the forecast and lead a move indoors if needed. These are statewide planning checks, not verified Onset venues or policies. Ask us to confirm the requested theme, program, availability and cost.

Before you pick the spot in Onset

Useful rules and places to check, each with its official source.

  1. Choose a real indoor backup

    For any outdoor gathering, arrange an accessible indoor backup before the party. National Weather Service guidance identifies buildings with wiring and plumbing as stronger protection; an open picnic shelter is not a lightning backup. This is national planning guidance, not a local venue rule.

    Official source (opens in a new tab)
  2. Assign a weather decision maker

    Choose an adult to monitor the forecast and decide when to move the group indoors. National Weather Service guidance calls for a designated weather monitor; confirm a practical route to the backup space with the venue. This does not establish local permits, shelter reservations or entertainer availability.

Sources checked 2026-10-04. Check the current venue rules before you plan. Venue guidance does not mean a venue has approved character visits.
