Thank you for your positive answer. It's said usually some policeman will check the passport when we cross the border (especially via Venlo). when I asked the secretary of our group, she told me without the passport, I can't travel outside and the information is from IND. I feel surprise too.
ID 只在荷兰合法,可以代替passport的。不过奇怪的是,我在德国定了酒店,问能否用荷兰的ID check-in,被告知是可以的。我现在想比较一下,从Venlo过境,和从Arnhem过境哪个被查得概率较小一些。如果有朋友有这样的乘车经历(特别是经Arnhem过境的),还望告知你们当时的情况。先谢了!
