Bus from Bruges to Amsterdam

Rome2Rio says 1 bus per day and takes 5 hours. Since trains are fairly frequent, and non-Thalys routes are 4 1/2 hours range at the same price, I'd go with that.

Eurolines has a bus service between Bruges and Amsterdam, I think they don´t plan far ahead as their website shows only journeys for February and March: http://www.eurolines.com/en/

Is there a reason you would prefer the slower highway sameness and discomfort of a bus over the faster rural beauty and comfort of a train?
