Hi Paul, Dylan.
I went on Oriana. I have some tips for Dylan... obviously it depends on where your going just looked

Arcadia!
Bregen, Geiranger, Flaam and Stavanger
Bergen, if your not on an excursion and you want to get to the viewpoint up the Mountain get to the funicular ASAP before the queues get long, its easy to find.
When you get back down you can check out old wharf "Bryggen" (you will probabaly pass this on left on the way to the funicular). Then the fish market is quite colourful.
If your luck you might catch the reflections on the waterfront. (I didnt). Also check out the Tall ships race it was due to start this week. Bregen was Rammed while we were there and the visitors died down later in the old wharf so i could get some un obstructed Photos (just).
Geiranger, not sure about this... if you go to Ålesund you can go up through the town and up to the viewpoint (some of Pauls pictures were taken from the top of here. About 400 steps but pleanty of stopping points if you want a break. I walked along the top to a Transmitter tower and there are various opportunities along the ridge for some shots. At the end just before you get to the tower there are paths leading down, past some man made lakes/ponds. In the town cracking reflections in the harbour of the coloured wooden houses. If you want to get to Alnes Lighthouse (in Pauls Pictures) you'll probabaly need to book a trip.
Flaam, Theres a Rail trip that goes up through the Mountain very pretty, Difficult to get pictures as you need to be both sides at once. If you get on the right hand side going up and you can change over thats the best method. There is a stop at the Waterfall for about 5 Mins so make sure you sit by a Door! Also its a good idea to be by a window that opens, if you sit on the Left hand side on the way up thats the platform side for the waterfall. So out and shoot, no time for Grads, Stoppers or Tripods! So you get the scenery etc mainly on the Right, and Exit of the Waterfall on the Left. It stops at the waterfall on the way down and up.
We got back and to Flaam and yomped up the valley back through the village past the church to another waterfall it was a hell of a yomp in the blistering heat (bit to much if i were honest) but there is another waterfall nearer the village, on the left hand side, unless your up for a big hike.
Stavanger, cant help on this one, as we did'nt call here...
Other advice, well if you have not cruised before i generally find everything is on a limit for time (Not to mention SWMBO moaning for me to catch up as i'm always behind taking pictures). Theres a lot to fit in, in a short space of time ashore. I took most of my Kit. In retrospect i probably wouldnt bother with my tripod (unless you have a travel pod). I used a 24-70 mostly, the longer lens didnt come out at all. Take any filters you have....
The scenery is stunning, you might want to get up early going down the Fjords especially Flaam so at least you get some good light. When we were there it was really hot only one wet day, the light wasnt always the best as by the time you were ashore the sun was well up.
Hope this helps!
Paul, Hi i've got some pictures to go through but have been very busy at home and work since i have been back with no time for PP
Hopefully i will get time for some processing soon
