Ms. P. Galore has 6 grandchildren and five children. So, if you add a spouse, that would be 16 ppl. Don’t forget the nannies, tho. Of course they have nannies with them, have you seen the bills for booze on these trips? No way the parents are “watching” their kids.
So let’s just call it about 20 folks, not including the P Galore and her staff/security.
7 Congress-people, their families, mega-donors, and certain, hand-picked pilots....and maybe their families.
