I am wondering if I am able to travel with this deal on 0630 am during holiday (26/12). It is not clear that the offer is not valid during holidays. It only says that it is not valid on King's day. I was confused by the response from the internet and NS chat. If you can clearly tell me, it would be very grateful.

Look at the subsection about travelling with promotional tickets.
ps. If you are making a return journey on the same day there might be cheaper alternatives. If you just make a single journey this is the cheapest option available.
