My FIL has a friend who owns a house in New Orleans near Bourbon Street. Next March, he's going to be in Austrailia for a month, and offered several people each their pick of a week to house sit. My FIL took the week of St. Patricks Day (March 12-20th, actually- slightly more than a week).
He also told FIL he was free to invite 1-2 people to stay with him if he wanted. So, FIL is offering to fly DH and I down (we live up in Michigan, FIL is in Florida), and cover food costs.
FIL and I are museum & history fans. DH would prefer a "Weed wacker to the eye over a day in a museum", but is willing to go along with us.
I've never been to New Orleans. Talk to me about the must do stuff, and the skip it stuff.
