In general, you should not feel bad about leaving while way ahead nor should you feel angry at another player if they leave while way ahead as long as it isn't a hit-and-run. But a hit-and-run is very different from what you are describing.

If it makes you feel better, announce 30min ahead of time before you leave, but this is just a courtesy. Never feel compelled to keep playing because you are ahead... only because you feel you have an edge and/or are having fun.

The guy who wants to up the stakes is trying (in part) to throw other players off their A-game by playing at uncomfortable stakes.

I like the idea of increasing the stakes or including a straddle at some preset time (say 11PM) to accommodate everyone's wishes.
