Work your nuts off doing 80 hour weeks for the period you are not going to be on the snow, then go on a 4 month holiday and not worry about working...!!!
Seriously, if you work at a resort, unless you are an instructor, you are gonna be getting very little snow, and stay away from FRANCE if you are gonna work... Just because...
You may be better asking on a forum like SCUK if you are doing the EU, as they will have far more people from the UK that have done this, unless of course you are aiming to do this in the USA or CANADA, in which case, the advice will probably be the same, work your nuts off, bring as much money as possible and just board...
