Group visits may be booked in two ways:
-Groups smaller than 50 may now book and pay in full online -here
-For groups larger than 50, or wishing to pay by invoice, you can use our online booking form -here
When paying by invoice, a 50% non-refundable deposit is due one month after the invoice is received. The final payment is due 14 days prior to the visit date, or the reservation is subject to cancellation. No refunds are available after that time. Groups will not be permitted to enter the Museum or Quarry until the reservation is paid in full. Groups may not reduce headcount of reservations less than 14 days prior to the visit date, but may increase headcount up to 24 hours prior to the visit date, based upon availability. We cannot offer refunds to guests who are sick or cancel at the last minute.
If weather conditions, including but not limited to rain, snow, extreme heat, or severe storms, significantly impact the operation of the Quarry and EFM elects to close the Quarry, guests will be given the option to reschedule their experience within six months of the scheduled experience or a full refund.To make any adjustments to your reservation, contact groups@efm.org or call 856-284-DINO between 10:00 am–4:00 pm.
