Nope that's not a typo.
Next year the Grand Depart is from Rotterdam - a 9km time trial. The first "proper" stage is from Rotterdam to somewhere near Antwerp.
Now this is a bit prepared for me, but I've just booked a hotel . Many of the sensibly priced hotels in Rotterdam appear to be block-booked already, so I've booked (cancelable) a hotel 15-20 minutes away by train. Reckon we'll be able to watch Saturday's prologue, the start of Sunday's stage, then the end of the stage as we head back towards home.
Excellent!
