Lengthy discussion on this on the Snowbird section last month.
Basic assumption was that unlike our parents, most of us have not had to do physically punishing labor for 40+ years before retirement.
We developed a different set of habits about such things as bicycles, kayaks, hiking, etc. We were also lucky enough to be able to travel more while younger and enjoy these things.
That makes us less likely to be satisfied with the snowbird destination which has group, clubhouse focused activity with limited physical activity potential.
Another noticeable difference is the boomers are more likely to spend a few years at one snowbird destination (say - California) and move to a new one (Texas or Florida) every so often.
As long as we are physically able - we are going to want to do those things.
The snowbird market customer base is changing.
