Hi,
I've just booked my dining for my Norwegian Fjords cruise in a couple of weeks. Chef's Table and Sindhu were available to book but Olive Grove was not and only once on board.
I did a similar cruise last May and found the hot tubs lovely but cold getting out. I'm not a big swimmer but some of the days would have been fine for swimming in and plenty of people were. I've cruised the Fjords a few time in May and August and swam both times as we had lovely weather 24-28 degrees. Obviously it isn't always like that and the weather can change quickly in Norway.
Last year I did the Loen Skylift which was amazing! The views were stunning and I loved it. Previously I took a boat trip from Stavanger through the fjord to see Pulpit rock. The scenery was again stunning and well worth seeing although seeing Pulpit rock from below was very underwhelming. This might have been because on a previous cruise with a different line I had climbed to the top.
It is also easy to do a lot of the ports yourself and see some amazing things.
Hope this helps and have a fab time😊
