Reminds me of the League 2 play off game, I panic brought a single for myself then instantly regretted not getting one for my son (he was pretty young back then and didnt know if he would cope) ended up easily getting 2 more. I gave away my original one to my brother who traveled over from Spain. was fine that we were in different seats we still met up before and after.
So glad I made the decision as it turned out a great day and my son still talks about it.
I appreciate a lot has changed since then, demand will be higher. But I would say that even though its not ideal, if you get a chance to go even if your group is split in different sections, do it. The day will be great anyway
