Sweden and Denmark

My husband and are will be taking a Baltic cruise in July. We are extending our stay at the beginning of the cruise for 3 days in Stockholm Sweden and then for 3 days in Copenhagen Denmark at the end. Can anyone help me with information on booking tours, places to eat, foods to try and shopping. I'd like to book a tour in each country prior to going but I'm not sure how to go about it. Thanks for any info you can provide.

For Stockholm tours, I suggest www.spb-tours.com. We used it for booking a private 2 day tour in St. Petersburg. It also does tours in Estonia and Germany.

When we did a Baltic cruise a couple of years ago, we used www.alla-tour.com for our St. Petersburg day. I know she has tour guides in multiple Baltic cities, and our experience with her company was outstanding.
