They don't cook or clean for themselves, they can simply rent out luxury accomodations wherever they land and if an idea hits them at any hour then some person is being paid to answer the phone and figure out what the heck it actually means they should do at 3am when they thought of it.
And then when they turn up somewhere, they talk solely about how hard they worked before someone tells them their next meeting, where dinner will be tonight and here's your private driver.
