Sorry if this question has been asked before, I tried to check. I am flying to SIN in the summer on the A380 with my family. We are all flying in Y. We have 3 children so the cost of C would be too high. I tried to ask my wife if I can fly C alone but you can all guess what happened then

The question is then, since I am BA gold, i reserved seats 20 BC and 21 ABC. In front there is business class. Are the toilets in front of me blocked for Y passengers? If they are not blocked, there is some distance from my Y seat to the toilet so it would not be so much traffic?
