Thank you.

Had not considered Gdynia.

Now planning a trip via the Sofitel in Warsaw ( as on sale at the moment ) then train to Gdynia and working our way back via Sopot to Gdansk Old Town then fly back

Is 4 or 5 days in each hotel for area a good option ? or would we be better splitting more Warsaw / Gdansk, and less time else where ? ( we have 15 - 20 days in November / December )

Last year we spent 2 weeks in Krakow and it was lovely, apart from very over priced airport ( and lounge ) for what we had.
