Getting a hotel in Oslo can potentially be difficult. In peak periods, when big fairs or conferences visit Oslo, tourists have been sent as far as Lillehammer (170 kms, 2h 15 min by train) to find accommodation. It would be smart to reserve a room in advance. There are also relatively few youth hostels, etc., for people travelling on a budget.
