If you have not spent any time on the slopes before then we definitely recommend a couple of lessons on the indoors slope , give The Snow Centre in Hemel Hempstead a call and you can get a discount via coolskijobs.com
If you are heading to work in Europe (or the Swiss alps) currently you would be covered with an EHIC card , this will change due to brexit on 31st December 2020, however we are unsure yet as how this would affect seasonal workers.
If you are working for a tour operator / chalet company then check their insurance cover, importantly this is all about your slope time, but also check that you are covered for theft / accidental loss etc. More importantly if you are working for an independent business (bars/restaurants etc) it would be wise to buy season insurance, we recommend MPI Insurance.
Have a look at French SIM card deals, these can be found on ebay or on the actual French sites. Currently you can use your UK data and minutes allowance in the EU, we are expecting this to stay in place after Brexit but always check with your provider first.
Bring cash and a card with you, you may not get paid for a while plus if you are working independently then you will need money for a ski pass.
Always take a stock of Lemsips/cold tablets /pain killers etc with you as this kind of thing is much more expensive in resort and you may not have a pharmacy to buy them from.
Bring a bag of wine gums in case you bump into me 🙂
Plug adapters… Bring them… Or a 4 way English adapter (with a surge protector)
Driving licence as you may need to show ID / hire a car etc
Ensure you have all your internet banking sorted before you arrive.
Make sure you bring warm clothes… Sounds daft, but you would be surprised.
