Mine has taken one suitcase and one big duffle bag. That's clothes, toiletries, books, pens, calculator, bedding including duvet (but not pillows), woodwind instrument, laptop/ipad, chargers, power strip, and various other bits and pieces - cup, plate, cutlery but not much.
When she got there she bought pillows, more toiletries and shower caddy, laundry basket, hangers, desk lamp, cushion.
She'll take her cold weather clothes and boots there later in the year.
DH is taking her guitar out there soon. She's going to buy an amp and bike secondhand, and a new printer.
When she was at boarding school she actually took less and less with her each year, and now she's a 2-hour flight away she knew there was only so much she could bring.
A lot of her stuff will have to go into storage over summer.
They actually have washers/dryers available for free in all the halls, and you can use an app to see which are available/in use, and also the app tells you when your laundry is done.
