In the past I've been very happy with local guides recommended in Rick's books. Now looking for names in Copenhagen. Thank you. Nancy
The Copenhagen chapter in his Scandinavia book does recommend some private guides. Some of them do group tours. too, but can be hired separately.
If you don't want to buy the guide to find out this information, don't forget to try your local library. You can often check out guidebooks there.
Thanks to you both
