They'll be full of nappies as no way would she pay for a diaper in the states. She has two kids in nappies for a fortnight. I would also bet she has snacks and stuff all packed for the kids as again, she won't pay for stuff for them if she can avoid it. She will also have her usual pool inflatables, smores kit and tea light to cook them on, the dusty 1950s fringed parasol for the beach and her trusty saltwater sandals and hats. She probably takes a full length body pillow to separate her and grandad in bed in case he gets overcome by lust in the nightWhich I’d understand if it was a load of hard cases which could be loaded on empty, but these are soft cases that already look full!
Also, bless her cotton socks she’s done her second Reel!
Once the nappies and snacks are finished, she has plenty of room for goldfish crackers, pumpkin puree and there's something else she always brings back from America but I'm fucked if I can remember what horror it is
