I need to change some dollars into Kroners. How should I go about this? Is it best to do this in the US before I go, or wait til I get to Denmark? Can I do it online? What about traveler’s cheques? (<----Note metric spelling; I assume that’s how they do it in Denmark!)
Use the ATM in the airport - just get money over there.
Both the airport and train station should have places to exchange money. Not sure how you’re entering the country, but assuming it’s one of these two methods, it shouldn’t be a problem.
This is what I’ve always done. You get a better rate that way than exchanging cash.
It’s how American Express spells it, even when the cheques are denominated in US dollars. Cite.
No – it’s “rejsecheck” 
“Cheque” is British English, and pretty much standard outside the US (and possibly Canuckistan?)
That’s another noticable difference between America and here. Bureaux De Change are available everywhere here with loads of different currencies.
Wherever they speak English. They don’t speak English (as a first language) in Denmark (except for the Crown Princess).
True. But as a general rule, the rest of us are quite proficient in English as well. Feel free to email or pm me if you need any info about Denmark. When are you going?
My wife is going later this month. She’s going for a wedding of a friend who lives there, plus she’s going with another friend who’s been there a dozen times or so, so she has plenty of help. Thanks for the offer, I’ll pass it along to my wife.
No sweat. And as per your OP: Just take out some money at an airport ATM.
It’s spelled with a Q in Canada too. See, for example, Bank of Montreal Primary Chequing.
I third or fourth the ATM suggestion, it’ll get you the best rate. The exchange kiosks in airports etc. tend to give you a worse deal.
Denmark in late September - may not be the greatest time of year to experience my fair home country, but on a pretty day, it’s something.
If your wife decides to go a little wild while buying souvenir, tell her to look into the VAT refund scheme. There’s a bit of paperwork involved, but if you decide on a large-ticket item, you can get a refund for (some of) the 25% VAT.
My wife asked me to solicit suggestions of fun things to do in Copenhagen and the surrounding area in late September. She is considering bus tours, canal tours, and perhaps a train trip to Sweden.
She also wants to know if she needs to book these things now, in advance, or if she can wait until she gets there.
Is Tivoli Gardens still open in Copenhagen? I had such beautiful memories of fun times there.
I got some of my best souvenirs by going to the hardware stores after I had had a few meals in Denmark. There I could find some of the unusual utensils such as the egg cups and little spoons that I couldn’t find anywhere else.
A book in English with suggestions on how to make a variety of those wonderful open-faced Danish sandwiches has been popular with friends and family for the last thirty-five years too.
Hamlet’s castle is in Helsingor (Elsinor?) not very far away from Copenhagen.
There’s a palace in Copenhagen and I seem to remember that the guards weren’t quite as straight faced as the ones in London are reputed to be.
Is there still a museum in honor of the Danish resistance?
There is a shopping area in downtown Copenhagen where no cars are allowed.
Your wife is going to have so much fun! She should try the fried eel. It is wonderful!
I’m familiar with CPH airport. There’s even a machine in the baggage claim that will take in dollars and spit out kroner. But there is also an ATM in the area right before the train station where you get information or rent a car.
As long as you have a typical American ATM card with the Plus logo or whatever you’ll be fine. I have a card from a Podunk hometown bank and it worked too.
Don’t tell her about the sex museum.
Copenhagen is, IMHO, one of the nicer cities to visit. Of course, people have different ideas of what constitutes fun, so…
The canal tour is recommended - it may be necessary to bundle up - but a lot of the noteworthy buildings look really good from the water front, plus you get a bit of a guided trip, too. (You’ll hear “this building was constructed during the reign of Christian 4th” a lot…)
The collections at Rosenborg Castle are worth a look, IMHO. Pretty nifty Crown Jewels, plus the building is a truly beautiful baroque castle.
Rundetaarn (the round tower) is another cool bit of architecture. Moving forward with the history/architecture angle, a rarely visited site is the ruins under the current parliament (Christiansborg). When excavating for the current building (the 5th paalce on the site, they tended to burn down), builders found ruins that date back to the original fortification from the 12th century. Interesting stuff, at least I thought so.
The little mermaid, otoh, is pretty bleh. She’s very little and she’s far out of the way.
If your wife is interested in modern art, a day trip up north to the Louisiana museum is not a bad idea. It can be combined with a trip to Helsingør - better known as Elsinore in that play about the brooding Dane - the castle (Kronborg) is impressive.
If classical art is more the way to go, Glyptoteket has collections of ancient art (Egyptian, Greek) as well as Danish and French art from the 19-20th century. It’s central, too.
Or she can go wear the credit card thin in the pedestrian area. 
ETA: She has to try a street vendor hot dog. Danes long for those to the point where there’s a hot-dog stand in the luggage pickup area in the airport, so you can get your fix while waiting for your suitcase…
Tivoli’s summer season ends on Sep. 21st, but there are plenty of other things to see and do in Copenhagen. Does she like museums? If she does, she could try the
[ul][li]Museum of Danish Resistance[]The National Museum where they recently re-opened the Danish Prehistory exhibition (lots of great stone and bronze age stuff)[]The Danish Jewish Museum - The interior design was done by Daniel Liebeskind, and even if the subject is of no interest, the architecture is still fascinating[]Glyptoteket - our finest collection of classical art (from ancient Egypt to the Romans).[]Tegners Museum (site only in Danish - for examples of his art click “Museet & Samlingen”) is about an hour’s drive away from Copenhagen, but both the surroundings and Rudolf Tegner’s art makes it worth while.[/li][/ul]
Christiania is worth seeing, too, even if it no longer is what it used to be 
A canal tour is nice as well. As for a bus tour, she should remember that Copenhagen is quite small, and if she can get her hands on a bicycle, it’s easy to just roam around. None of these things needs advance booking.
ETA: Nice list, Spiny Norman. Strange that Glyptoteket is the only place that’s on both our lists…
