What's most important things to take when going abroad?

So I go to Majorca on Wednesday for 6 weeks to work in entertainment team at a hotel.
So far my important things are

Passport
Travel documents
Mobile and charger
Bank card and some cash
Shades
Suncream
Bikinis
Shorts
Dresses
Tops
Sandals
Beach bag
Toiletries
Nail polish

I can't think of much more but I guess I'm getting too excited 😊
Also I get smaller things over there.
