I was in Lafayette on Friday and Saturday, Baton Rouge and Hammond on Sunday, and New Orleans on Monday. I expect to be New Orleans tomorrow (Wednesday) and again on Thursday. Right now, I just take a request in a particular city and then look for other opportunities for service in the same city.
If I had easy access to an inexpensive place to stay in a given city, I think I would plan trips of maybe two or three days and announce them ahead of time. To make a circuit of all four cities every few days might be best of all, although many things would have to come together for that work.
