Planning to go to Copenhagen, Oslo and Helsinki in addition to Stockholm and driving Estonia, Latvia & Lithuania on a 3wk trip. Trying to determine how much time to spend in Oslo and Helsinki. Oslo 1 day-Bergen area 2days back to Oslo for 1 day or need more time in Oslo before train to Stockholm? I've read that 1.5 days in Oslo is enough? We're taking the overnight ferry from Stockholm to Helsinki. Same question--how many days in Helsinki to get a good snapshot?
Thanks for your help
