Hi Tore,
I specifically pointed you to the south bank of the river simply because the sun is in your back when taking pictures.
At the end of the Maasvlakte you'll find Slag Maasmond where all ships pass for Maasvlakte, Europoort, Botlek and smaller port areas. By contrast, Hook of Holland is on the North bank and vessels to the Maasvlakte do not pass there.
I already gave you some info about the Landtong Rozenburg. Rozenburg is a former island, now a part of Rotterdam with abt. 12.000 inhabitants perched between Botlek and Europoort. East of Rozenburg you'll find the Botlek, but unless you know the back alleys it's hardly possible to take a decent picture. In the city of Rotterdam you'll find the remaining containerports, the Waalhaven and the fruitterminal.
South of the Europoort/Botlek area, on the island Voorne-Putten, there are two historical towns: Brielle, which was the first to be liberated from the Spaniards during the 80 years seccession war in 1568. And also Hellevoetsluis which was a naval base until Napoleon put an end to it, preferring Den Helder because it was not so close to Great Britain. There are still remains of the citadel incl. the oldest graving dock on the continent. Om the north bank, opposite Rozenburg you'll find Maassluis, known for it's tugboat museum and other maritime venues.
As alternative hotels I could suggest the Bastion Hotel in Brielle (
www.bastionhotels.nl) alternatively the hotel Rozenburg. (

Have a good trip and please do not hesitate to contact me for further info.
Robert.
