For me, whichever can give me the fastest slot, ill take it. I believe priority will be given if you have other siblings. You may wish to let the centre know. Otherwise, if you think N1 are approachable to changes then maybe follow the younger ones to Centre B. Because to me if the centre is nearby to each other no issues of separate centre unless it is hectic/chaotic. You know sometimes the elder dont like changes hence maybe you can move the second one later when you have slot?
