Hi! I am also on that Volendam cruise and am a widow traveling solo. There is a rollcall for the cruise you can join - a Meet and Greet is being scheduled... so you can meet others. I believe there are daily "solo luncheons" on sea days where you could meet people and maybe someone to dine with (I have open sitting this cruise, but like to dine later in the evening). Join the Roll Call!
