That sounds so cool. We have talked about doing something similar. We've never jumped off the deep end but we've got our toes in the water.
I think the success of this endeavor will depend primarily on what type of parents you and your spouse already are. It isn't about being planners or spontaneous. It is about your comfort level to seek out different opportunities. So, for example, when you heard about the eclipse this summer, have you thought, 'hey, that sounds like fun, lets drive 10 hours rent a hotel room watch the 2-minute eclipse and then drive home'?
I am the planner in our family and I would be the one who would have to totally make it happen. My husband is a great marching band leader but I have to get him to the field, give him a little prep time and then it's on to the show and he has the kids totally rocking whatever it is we're doing.
Our kids know our dynamic. When Dad comes bursting in with his exciting idea that we are going to sail to Bermuda with our best friends, leaving next week, on a Cat then the kids blink and say 'wow, sounds like fun. Does Mom know?'. On the other hand, when we're sitting around looking at each other bored out of our skulls, the kids know to get Dad in to the picture.
Finally, what do your kids do when you go off on junkets? Are the dragging their feet or participating? If they aren't throwing themselves in whole mind and body then I wouldn't say it is off but I would start 'practicing'.
Good luck and have fun!
