"I haven't seen your maths, but it may not be that much - assuming you're going to save all the extra money is optimistic no matter how good your intentions are right now (more work hours is more incentive to outsource as you're so busy, worse job is more incentive to treat yourself, more income means less pressure to make that extra cut to your spending)."
we're still baby 'staches in my house, but there's a fair probability that we can save 90-100% of the extra money. We have a house that we are well on-track of paying off quickly (and possibly sooner if we refi - although I'm still crunching numbers on whether that makes financial sense or not). Young SM2b still has several more years of spendy daycare but our neighborhood school is within biking distance of home and is of an acceptable (albeit not pre-ivy league preparatory, but he'll get over that) quality such that once daycare is paid for, that'll chop a lot off our monthly expenses. However, you are right...its likely my hours will increase as a promotion includes additional stress and work. (There's also the additional issue that if I stay in my present position I might get to start teleworking a day or two each week, whereas the promotion doesn't have a flying feathers chance in Hades of doing so). So, there might just be more outsourcing of food preparation or (worse in my opinion) outsourced caretaking of young SM2b for after-school activities. I appreciate the discussion here, as you all are helping me flesh out issues I haven't really considered (including the need to do a risk-assesment of whether 100% of all the added money will actually go to savings).

"How likely is it that you will get promoted and when would that happen?"
More likely than not. I've been groomed for the job. However, my boss leaves this year, so the person selecting changes too. There's no guarantees in life.
"How do you deal with working with people you don't like/see eye to eye with?"
Not very well. However, my senior supervisor is my senior supervisor no matter what position I'm in, so I'm screwed on that point no matter what.
"Are there other companies in your area that would be looking at someone with your skill set?"
Yes, but not doing exactly what I'm doing - and I'd be on the opposite side of "doing good things for the world".
"This sounds like a pretty big pay bump - is there an increase in stress level/hours worked?"
Definitely an increase in stress level and while not a guarantee, I think its highly likely that the hours worked would increase as well as the requirements to travel.
"I am all for making as much money as possible but if it takes a detrimental toll on your life it may not be worth it."
This is the conclusion I am leaning towards as well...however, as a baby 'stache, I'm having issues getting over my ego of "I'm not going to move up any higher", "I'm not going to make the big bucks"...I know I'm whining, and I know once I'm FI and have an FU 'stache, I won't care...
