You keep posting this over and over.
Do you not realize that there have been cruise ships built since 1995 and they are nicer than the mobil home you live in?
Most of the newer ships have several sit down restaurants. Some you have to pay for, but they are very nice. Do a little research.
Yes, the 4 night carnival cruises out of Mobil and New Olreans is going to have a bunch of people who look and act like your kind of people.
When you get with the longer cruises and the more expensive ships, you get away from the trash.
