They should both be going dormant at this stage of the year so, as long as they're well packed up and have some air around their heads and don't get squished by packing cases they should be fine for a few days.
When we moved from Harrow to Belgium I brought a Japanese maple, a rhus typhina dissectum, a Worcesterberry, a pot of proper English raspberries and a few other plants in smaller pots with us - all gifts or having special associations for me. They spent 4 days in a sealed removal truck in June and were none the worse for wear. I still have them all 24 years later - except the acer which succumbed to a very hard winter one year.
