Coming off of a RSSC cruise on Voyager, also in Scandinavia, expectations were high. Oceania, while not the same all-inclusive experience, offered better dining and an altogether better value proposition as well as a more lively crowd. Our PH1 suite, 8030, was extremely well located, quiet, clean, and well maintained though wardrobes and bathroom were a bit small, at 6'3" had to duck to use the shower. Early embarkation was a breeze and luggage delivery was less than one hour after getting access to our cabin. Specialty dining at Polo and Toscana were great and offered twice in each restaurant as suite passengers on the 10 night cruise. In MDR suite status seemed to ensure (not an advertised perk) seating at prime 2-top tables by the windows unless we requested group seating. We opted for top-flight beverage package based on number of sea days, but wouldn't opt for this again as we felt "pressure" to make the most of it.
Have read other reviews that pan this ship, I understand that there was an unfortunate fire and norovirus outbreak on the ship which seem to have pushed down the overall score. Our experience was top-notch and we would have no reservations about booking on Insignia again. In fact we enjoyed the cruise so much we booked another on Riviera for next year.
A few more details: able to store large suitcases under bed when left "open" as they were too thick otherwise, storage in bathroom at a minimum, nice toiletries re-stocked frequently. Two chairs and table by veranda and sofa made for comfortable areas for reading and in-suite dining with butler (mostly took advantage of this for breakfasts on early tour days). Balcony was a bit small with two chairs, no ottoman, though the horizontal bars of the metal railing allowed for a place to rest one's feet.
Booked a private tour with a driver in a 4x4 who picked us up directly from KEF airport and took us on a 10 hour tour which included the Golden Circle highlights as well as a snowmobile ride on a glacier. Well worth the high price - 217,000 ISK as it was a once in a lifetime experience and made the most of our ~24 hours in Reykjavik.
This was our last stop on our 10 day cruise. Took an Uber from the terminal to our Hotel, the Sheraton Stockholm then did a self-guided walking tour. It was Gay Pride week so the city was decked out in rainbows and had a vibrant atmosphere.
