we spent 6 days out of a 2 week trip on the soutbound voyage of the midnatsol from kirkenes to bergen (note- we got on in kirkenes). this was the first cruise for my family, which includes 2 daughters ages 13 and 17. i was very anxious about them having enough to do, about seasickness and about the food- but i needn't have worried about any of it- it was a fantastic experience for all of us. the scenery was spectacular, the ship was well appointed, i loved the frequent stops, the food was interesting and there was always something for everyone, and we had 2 wonderful excursions. a few other points:
-the folks on board are mostly older- not sure why exactly. it is a great cruise if your mobility is handicapped because you can just sit and watch and be amazed- but i think it's great for families too. my daughters didn't make any friends which was a slight disappointment
-the folks on board seemed to keep to themselves more than i'm used to with fellow travelers. also, many tables for meals seat 2 or 4 so you may not have to sit with anyone at meals. for us this was ok. -it's a casual ship- not dressing for dinner (loved that)
