My girlfriend and I are celebrating New Year's in Copenhagen, but are flying into Stockholm a few days beforehand and plan to make our way south via train. We could use some advice on a few subjects:
we're planning on taking a train down to Malmo before we head on to Copenhagen. What's the best way to do this? Is there a Scandinavian equivalent of the Amtrak/ light rail/ subway combo to get to New York City from the surrounding areas?
we'll likely have one day each in Stockholm, Malmo, and Copenhagen. What should we make an effort to see?
any recommendations on places to stay in the above cities? Not opposed to hostels, but would prefer to avoid sharing a room with strangers.
4) Cold weather gear-
we're coming from Colorado, so we won't be wholly unprepared, but what sort of things are we going to want to have with us to deal with the weather up there? Layers, brands, materials, etc.
is it better to use cash or credit? We've got a card with no international transaction fees fwiw. Sweden and Denmark both have their own currencies, correct? Anything else we should know here?
scams to watch out for, customs to be aware of, helpful phrases or other things to know?
Thanks in advance.
