We (my brother, sister-in-law, husband and I) were also on this cruise. Given the wonderful quality of the reviews (see Purple Traveller's thread
and United_11's thread)
I’m just going to give some comments on our excursions sans pictures (the ones already posted are fabulous) in the hopes that the information will be useful to those contemplating or already booked on a Norwegian cruise.
Southampton – we arrived a day early using Smiths for Airports car service from Heathrow
