"A while back some guy on here was talking about his experience working as a sort of personnel manager for a billionaire and how things are just wildly different for them.
The specific example he used was how things work when these people want to go on a trip, and give any notice at all to their employees.
What happens is that an advanced team gets sent ahead by a few days to scope out the rented/bought location and report back exact dimensions for closet space, drawer space, etc. People back at the home go through the clothing, jewelry, etc, and draw up a priority list which is sent to the advanced team. The advanced team then spends the next two days purchasing the list of items. Entire wardrobes, jewelry sets, makeup kits, bathing supplies, etc. Anything they cannot get (not enough time, or is one-of-a-kind like the family heirloom watch the rich dude wears every now and then) is relayed to the house-team. The family's schedule is arranged such that the moment the family leaves the house on the day of travel, a whole team of people rushes through and packs up all the remaining items (only after the family leaves, you wouldn't want to deny them access to their items for even a few seconds) which are then sent ahead to the airport while the family has a lunch or something somewhere. Upon landing, their luggage takes one route (direct) and the family takes a similarly indirect route (unless otherwise directed) such that by the time they get to the location all of their items are not just unpacked but in their proper organized locations and ready for use without any of the advanced team ever being visible to the family.
What happens when the family leaves the location? The same situation in reverse, but quite frequently all of the repurchased items are just disposed of in some method. It's just easier, if not cheaper, to rebuy them each time the family goes somewhere if they aren't travelling to too many different locations in quick succession."
