Never ridden at either of those parks, but have skied at Åre and it stunning.
Malmö and the south is the driest area, as stated Sweden is a long long country.
Clearly the three largest cities of Stockholm, Göteborg, and Malmö offer the best employment opportunities, especially for a non Swedish speaker. Having native English is a bonus though.
Unemployment for the younger age groups is relatively high, no idea how it compares with the UK though. Having said that the gang of people I met at Swedish classes when I moved over had no issues getting jobs despite no speaking the language.
Getting the personal number is key though, a classic catch 22 situation. Its tricky, but no impossible, to get a job without one, but renting somewhere and setting up a bank account is somewhat frustrating.
