Hi Bob E; I've been through the Canal twice and I've been on Veendam, sister to Statendam, but I haven't done the two together :-)
I don't know what type of cabin you are thinking about, but if there was ever a time for a balcony, this is it! The railings can get very crowded, especially going through the locks; so it's really nice to have your own vantage point. We pretty much camped out on our balcony all day, and took full advantage of room service.
I really loved Veendam, especially the size; it dosen't have all the choices of the larger ships, but everything about it was impressive, and that from a dyed-in-the-wool Princess fan!
If you have any specific questions, I'll try to help. But other than "get a balcony", all I can suggest is "have a great time!"
