I think the $5k/week is a great plan so you know you're set till your death bed.
What would you do? What would change in your life?
I'd buy a moderately big house for DD and I, and ask my parents to quit their jobs (which they hate with a burning passion) and come live with us in our walk out/apartment basement :) Hire a chef and a maid and just play with DD all the time.
Edit: you can view this as non-taxed income.
