楼主给自己买一份博物馆通票就够了。对于儿童免费的博物馆,你的孩子只要跟着你直接进入就行了,当然需要出示证件证明他的年龄。网上的原话:Under-18s do not need to pick up a free ticket at the ticket office if they are accompanied by their parents, who have an entry ticket to the museum (or monument). They walk through with their parents, and will only need to show their ID.
