Welcome to Reykjavík! This is probably the ideal city for someone in the age band of 25-29 (rough range). As your fellow NYC bankers all do the same old boring Italy, Paris, London trip you’ll do something completely opposite. You’ll book 9 straight days in Reykjavík Iceland instead. Not only will you have more fun, you will have no interest in returning after about 9 days.
Since it is a small and freezing island, you’re motivated to see everything and it is surprisingly fun. Chances are low you ever return again since 18 days would represent guaranteed alcohol poisoning, at least 1 damaged suit and the ability to recognize everyone by the end of day 18. Go for one week (which is basically 9 days when you add the 2 weekends) and you’re good.
Before jumping in, you don’t need to know any other language basically everyone speaks english in Reykjavík.
