Of course, I have no way of actually gauging how many people in different places in the US might actually come and see Wrexham, and we will never know because, as you see, the big clubs will sell out these stadiums by themselves. I'm just trying to say that I think Wrexham are right now a much bigger draw than, say, Notts County or Bradford City.
Either way, absolutely, it's a great deal for them. They're milking their celebrity status very well. Must be a great experience for the players as well (assuming they won't get humiliated
).
The human body actually has a built-in clock that regulates your sleep/wake cycle and activity levels. That's called the circadian rhythm. It is actually by itself not perfectly attuned to the 24h day (weirdly enough), but it uses daylight as a trigger to stay in sync with the Earth's day/night cycle. (Which is why lights in the evening, such as a phone's blue backlight, can cause sleep issues.)
So jetlag is really a natural phenomenon, you can't really not have it. Of course, you can do things about it, by taking in sunlight (to cause the circadian rhythm to adjust quicker) or taking melatonin (which is a hormone that controls the circadian rhythm), and obviously how you experience jetlag will vary from one person to another (like any condition), both depending on your body and what you are doing during the jetlag period (your sleep/wake rhythm, how busy you are, etc.). And how you experience your voyage will also affect things, cause e.g. if you skip a night's sleep, your rhythm is off anyway. How it actually feels and how disturbing it is also depends on which direction you're travelling in.
Anyway, all that to say that jetlag is real, but that it's not an one-size-fits-all thing.
