Hello!

We are flying into Oslo in early September for one day and flying on to Munich the next day. Any must see suggestions? We're 3 active women, and not really into museums. We will be staying in Central Oslo.

Also wondering about luggage weight and size limits on Norwegian for our flight to Munich. We paid for carry-on and checked bags, but on an earlier trip to Europe this year our checked bags were delayed two days in both directions, so I really don't want to check our bags. Their policy states your carryon and underseat bag must weigh less than 10KG total, which is not very much! We already paid for the checked bags, so I'm wondering if they will be okay if we're over, or will they actually make us check it?

Thanks so much!

They will make you check bags.

You could visit the Vigelund sculpuures in Frogner Park. Even if not into musuems try visiting the Viking Ships museum.
Have a look at the Opera House.

Plenty to do in Oslo, just be prepared for sticker shock when it comes to eating and drinking.
