Youth hostelling again

Youth hostelling provides such social fun: the grand children, the other guests, the people running the youth hostel, and the kitten that the people running the youth hostel have.  This year, we went to Cornwall, to Boswinger, hiring a family room as usual, but for a day longer than usual because it takes so long to get there.
Getting there, we went via Devon, and popped in to eat our picnic lunch at my MiL's, where the children enjoyed playing her square piano, the one that used to be in the Green Room at the Old Vic, and sounds great when you play Bach on it.
Then we had three days to explore:

• the Lost Gardens of Heligan
• the beach at Porthcurnick, where the grandchildren built such a splendid sandcastle that the tide took six minutes to wreck it.
• a day at the Eden Project
