We will be in Copenhagen for a half day, a night and another day. The first partial day we plan on visiting Tivoli Garden in the late afternoon and an evening performance at the Glass Hall Theatre. I assume the performance will not conclude until 21:00-22:30 hr at which time we will return to the ship docked at Langelinie. Is there a bus we can board at the train station that will stop at Langelinie or a combination of Metro (perhaps from the Train Station to Osterport Station) and then a bus to Langelinie which will operate in the late-evening?
On our second day in port we plan on taking the S-tog in the morning to the Louisiana Museum of Modern Art and Kronborg Castle. Can we board a train at Osterport Station and get to the Louisiana and Kronborg without changing trains? Our ship does not depart Copenhagen until 17:00, might we be able to include Frederiksborg Castle if we make a "loop" from Osterport to Louisiana, then to Kronborg, then to Frederiksborg and return to Osterport Station?
