I was on the same sailing as you, plus the 7-day sailing the week after. It was interesting to read your thoughts. There were even more kids the second week and I observed several rounds of tag amidst the scenic cruising.
I mostly ate at the MDR in the evenings. I too was surprised dessert was ordered right at the start, but they did wait for everyone to finish each course before bringing the next. The Lido food didn't seem too appetizing in the evening. I was a bit disappointed that in the second week, the MDR menu was almost identical to the first week, so it felt like deja vu. Ditto for some of the shows.
I had been to Gothenburg before, so was disappointed we didn't get to go to Bergen, and then charging almost $20 for the shuttle bus. I ended up using public transportation though it was confusing. The second week, they had replaced Stavanger, so we got to visit Eidfjord again. It was a nice place, but visiting a different place would have been preferable.
Overall, the weather was beautiful for most of the 2 weeks (except at the very end, for a rainy day in Flam), so I'm grateful.
