On the SEA/MCO leg the flow of coach passenger through first was endless and truly annoying, despite the announcement that all passengers are required to use the lav in their own cabin. On the MIA/SEA leg there were only a few coach passengers who used the first class head and that was durng the service, which is not problematic.

I don't have a problem with people removing their shoes, but taking off your socks is a bit much.

I don't know whjensen. I guess the difference in people on the SEA/MCO leg and the MIA/SEA leg is like the difference in people that you are likely to see at Walmart vs. Nordstrom. Just different. We all try to be comfortable when we fly, but there is a difference between comfortable and just plain sloppy.
