It sounds like you don't want to get stuck in the trap of working-spending-working harder to spend more and all that, which is good. That being said, I hope that I'm in your shoes in two years. Krewcial's life sounds nice, I hope that I'll be able to pull that off after graduation. See how flexible the company is. If they really want you, see if you can cut back the hours or telecommute: do the work at home in the morning and take the rest of the day off. Of course I don't know your situation so I'm just railing off things that sounds good to me, but I'm sure you'll work something out. Good luck with whatever choice you make.
And if you have the time, may I suggest you read "The Overspent American" by Juliet Schor. It talks about how to avoid the workaholic lifestyle that you sound like you want to avoid.
