$500 million?
1. DW would design a Prevost conversion interior that is not as "glitzy" as most we see. Tasteful and home-like. Then we'd pay the premium to expedite the build.
2. No TOAD required. I would rent a luxury car or limo service wherever we were staying.
3. Hire a coach driver, for those trips you don't care to drive to.
4. Join an executive jet program (e.g. Net-Jets)to go along with #3.
5. Buy a site @ Bluewater Key, FL for wintering.
6. Consider buying Beach-front property on Cape Cod and add a pad with hookups for summering. Once we are done touring the country of course!!!
