Some useful sites to check for the information you need are www.visitcopenhagen.com and www.sightseeing.dk I have only been across the Oresund bridge by car, but I believe you can take the train from the Central Station in Copenhagen to Malmo and the cost is about £12.00. The HOHO tourist buses stop at the cruise terminals which will either be City Terminal or the one further out near the Lttle Mermaid statue. If you dock at the furthest one, there's a bus that takes you to the city centre, also a Tourist Information Office where the helpful staff are happy to advise you about tours. A taxi into town is quite reasonable and they stop next to the ship. If you haven't been to Copenhagen before walk along Stroget the main shopping street with its excellent shops and pick up a canal boat tour from Nyhavn. It's a good way of seeing many of the sights from the water. Happy cruising.
