Think we have the same mindset. My Wife has been home with the kids since she was 35 and this last year so she could be with the kids. Once we knocked down the debt and stopped trying to "keep up the the Jones" it's amazing how much less money is needed each month.
I have a 2 year goal that will semi retire me too, if it happens I will be traveling the world. I'd like to take 2-5 years and just travel, but my Wife doesn't see herself as a nomad type and wants to come home after each trip and take time to plan the next one. I'm much more willing to just go with the flow and she is the planner. We will see how it all works out, but either way I want to see the world before I get to old to enjoy it.
It's amazing when you sit down and calculate the Cost of going to work. If one parent can stay home with the kids you can save a small fortune. We got down to one car that we only use for weekend road trips, no commuting costs, less insurance, less work cloths, less restaurants, no daycare, no holiday camps, no summer camps, etc etc etc ... it takes an entire job just to pay for all these people to watch your kids.
