I am slowly catching up on my DIStime. And finally get around to comment! Red-eye flights aren't fun.
We have them usually travelling back from the US to Europe and with the time difference on top it is rather exhausting. But last time I found out that using earplugs makes such a difference! And if you manage to get some sleep I agree it is the perfect way to adjust quickly to the new time zone.
I don't understand why online check-in took so long for you. I think for us it was a 5 minutes procedure and I loved it.
It sounds like you are a perfect example that it is possible to eat at WCC without taking part in any of the fun stuff there. The good thing is that it is optional and that nobody is forced to participate. I guess they realized that you looked tired and therefore did not play it up too much for you. But a long wait for the food does not sound very good...
