I can sympathise with all those who live at a distance from their families. We have been sticking to the rules throughout and were longing for this particular restriction to be relaxed. We did however try our own version la It is achievable in a day, just, but not advisable. Our DD lives 220 miles away, that's an 8+ hour journey there and back. They left home at 5 am and headed home 12 hours later. We had roughly 8 hours together, and they didn't enter the house. The older girl and I comically kept practising Patrick Swayze's moves in Dirty Dancing, "this is your space, this is my space," but the 4 year old was very subdued and overwhelmed. We provided a picnic with their favourite foods and lots of handwashing with soapy water in 4 pint milk bottles. Whether it was a success or not who knows, we did get to meet. DD says they won't be doing it again because it is too far in a day.
