请各位大侠帮忙解答一下下面这个问题，好吗？急。谢谢！
7.3 If accompanied, please provide full details of up to two adults who will accompany you, including their passport numbers and your exact relationship to them.
Please provide details of accompanying adult’s full name, date of birth, passport number, address and telephone number. Up to two adults may be listed as accompanying you (the child). These details will be recorded on your (the child’s) visa. If in the future you (the child) want to travel without the named adult(s), or with different adults you (the child) will need a new visa. If the adult(s) you are accompanying to the UK already has a UK visa , or does not require one, please
provide evidence of this
请问关于此条，如果儿童去
英国旅游，是必须至少要有两名成人陪同吗？而且两名成人的信息都要提供，并记录在
签证信息中。如果旅行时，当时提供的两人不能陪同出行，则此
签证失效。
请问是这样的吗？我和朋友两人带两个女儿去旅游，是不是需要把我们两人的信息全部填写进去。这就意味着我们出行时，是不是必须四人一起，否则就不行了。

Up to, means 'at most', not 'at least'.
But, you must be together when you are in the Border Control (where visas and passports are checked). Of course after the visa check you may separate with the kids if you feel it is necessary.
If I understand it correctly, at least one of the adult should be with the children otherwise they cannot enter the UK Border Control.
