Dining time--is there a mad-dash table scramble??

We cruise often, and so enjoy the open seating dining hours on Regent and Silversea. We like to eat rather late, and usually enjoy the private time of a table for two.

The prospect of large table/single seating dining is less attractive to us and has made us reluctant to try river cruising.

What's the situation on the Amacello?

Thanks!
