We lived in this situation after Katrina and Rita.
We had one family's RV parked in the driveway and we provided shoreties (electricity and water hookups).
We had another family stay with us for a prolonged period of time as well. We turned our living room and 1 bedroom over to them.
We gave thanks to God that we were intact to help our friends from the New Orleans area out!!! We all worked together to get along and make things work together.
