Son’s family won’t accommodate grandma when she visits

DEAR ABBY: My son and his family live six hours from me. I can afford the gas to drive there, but paying for a hotel room for two nights is beyond my means. My son is a stay-at-home dad of seven children. When I asked his wife if I could stay at their place, thinking one child could make a pallet on the floor, giving me their bed, she said she didn’t want to put their child out.
