I totally get what you mean.
But don'tbelieve work/champagne/Eurostar is all that glamorous. In reality it means pleasing your boss, networking with colleagues, trying to impress clients...you cannot really relax and enjoy it, as even on the Eurostar or in a restaurant with fizzy... You are actually working.
IMO corporate do's and trips sound better than they are.
I worked in that environment for long enough to know that.
Being a SAHM works for us as a family. I now work part time, no proper career, but that is fine with me. Most days.
Some days I feel overwhelmed by the mundane repetitive tasks that go on and on.
But I love spending time with my kids, having the luxury of having a doggie (and walking her).
To be fair, I was close to a burn out when the kids were small, it is HARD WORK. And at times boring. When they got older the balance shifted. Life became easier for me, and harder for DH.
Also DH is sad to always miss assembly, school play, sports day etc.
Don't make the mistake of idealising DH's work. He probably has to suck up yo bastard bosses and clients 
And your life will get easier.
What work did you do before kids?
