Another Copenhagen question (I'm leaving soon and getting very excited...and antsy): Can anyone give me a general time frame for visiting both Amalienborg and Rosenborg? I know that they are near each other and joint tickets are offered and, if possible, I'd like to do them on the same day and perhaps in a single afternoon. I'm a history buff, so I expect to go through them carefully and do the audio tour at Rosenborg. I understand that people go through sites at different paces, but any input with be appreciated. I would be doing this on a Thursday, Friday, or Saturday, if that makes any difference.
