Thank you all for sending your experiences in this topic. 

It seems that the consensus is that the dry shippers works just fine even for 3-4 days. It is necessary to cool down the shipper a a few days ahead of the shipping date by filling in liquid nitrogen couple times. The grids are stored as they normally are in regular liquid nitrogen tank. Just before the dry shipper is picked up,  the liquid nitrogen left inside is emptied and the tank sealed. It is recommended that the tank is filled with liquid nitrogen immediately after arrival to destination.
