Cancellations and/or Date Changes

Inclement Weather

Please DO NOT assume your activity is cancelled. An inclement weather refund will not be issued to “no shows.” We hold programs rain or shine, and cancel only for heavy rain, thunder and lightning, or icy conditions. If we cancel, we will try to reschedule for another date that works for you. If we cannot schedule another time, a full refund will be issued. You will be contacted via the phone number provided on your Reservation Form and we will try to contact you as soon as possible. The Heard Museum closes when the McKinney Independent School District cancels and follows delayed openings. Your field trip will be considered cancelled by us under these conditions.

Cancellations without penalty

The Heard Museum must receive a written cancellation notice 4 weeks prior to your field trip date.
