Hello! My mother (65yo) and I (41yo) will be arriving in Oslo after an NCL Baltics cruise on a Friday in early June. I booked us the Thon Hotel Cecil for our overnight stay prior to flying home the next day. What would you recommend for us to see in Oslo? We were hoping for more time on the ground there, but getting home to Boise didn't leave us with a lot of great flight options! My mom really enjoys doing hop on/hop off tours, so I was thinking that would at least provide us with a general look around Oslo? I appreciate any assistance you can provide! :)
(Note: NCL booked our flights and we can't edit our travel dates. I will visit again someday for a longer period of time!)
