Valet parking and drop-off at the main entrance

Valet can be useful when a child is ill, mobility is limited, the visit is urgent but not ambulance-level, or a caregiver needs to avoid walking from the garage.

Where valet is located

Before you use valet

Ask whether the vehicle will be charged garage rates, a valet fee, or a validated patient/family rate. Rates can change.

Accessible arrival

If wheelchair assistance, escort help, or a shorter walking route is needed, tell valet or front-door staff immediately.

Discharge pickup

Ask your care team where pickup should happen after discharge because some units or departments may route families differently.

When traveling with a sick child, stroller, wheelchair, oxygen, or equipment, choose the route with the fewest transfers even if the travel time looks slightly longer.
