We have the (free) tickets booked for the Natural History Museum at the weekend. 1 group booked for 1pm and then group 2 who joined the day out later at 1.45pm (but 1 person in Group 1 has their ticket booked with Group 2)
How strict are they on people arriving and entering at the exact time? If we arrive a bit late (travelling in so could be delayed) or the second group are early/ late will this be a problem?
Thanks!
