Depending how old your son is and the "babe in arms" thing isn't an option then you only need to buy tickets in the same area really.Let me know how it goes. My son keeps asking to come with me but I can't ever get 2 seats together these days
Once you are in you can squeeze in 1 seat or if you are lucky there will be ticket holder close by that hasn't turned up.
Do it all the time with my lad.
