Genuine question because it would honestly make certain things in life, or at least during wedding planning, a lot easier, but it would make things a lot more difficult.
On the plus side, it would take out the need to do a table plan, which is a big thing, because it's not just the display, the ideas of how you do the display, how you put it up (does it go on an easel or a stand or have it's own legs or what?) or about everyone who tries to get involved and say who they will or won't sit with or anything like that, but it is the sitting down and thinking which personalities will mesh well, who is going to clash and who will bring the drama and who will calm the drama. It's about who is going to be shy or feel awkward, who gets nervous and word vomits all over who they are next to (and how the person next to them is going to take that) and all of the other bits that you worry about when you're putting people together for a stretch of at least an hour and a half. If you tell everyone it's a game of musical chairs you take the stress out of it for yourself, but then the problem is you pass it onto your guests and for us that would be horrible for a few people, because a few of them are travelling to the wedding on their own. For people that don't know anyone, it would be really hard.
As if passing the stress on isn't bad enough, and let's face it, it would be bad enough because some people are quite vocal about their disapproval of certain things at weddings, if you've planned a plated meal like we have, it would make it impossible for the venue. I read of a wedding group recently that someone was trying to do a plated meal but without options, so if you could find a dish that worked for everyone then yeah, maybe that works, but we have multiple people with allergies, people with multiple allergies, dietary requirements and sensory food issues, so unless we did something like chips, which let's face it, is not a meal, it wouldn't work.
I mean, I suppose the answer to all of that is to have a buffet, but I would still worry that it means guests who have come on their own would struggle, and people you would genuinely like to introduce may never meet, and also buffets are, at least to me, somewhat problematic, because it all just feels like snack food and a wedding is a long day (or at least ours feels like it could be) and I need more than snack food to get me through it, and I'm sure I'm not the only one.
We started on our seating plan weeks ago and honestly found it a struggle, as many people do, but when we sat and looked at it again, pretty much determined that we were going to get it done that evening come hell or high blood pressure, we didn't even argue. We debated a couple of things, looked at it from personalities and also the maths of how many people fit on each table, but then it didn't take too long to come up with something that we thought actually fit the majority of people or was at least the best that we could do.
And if all else fails, or someone tries to bring the drama, or a couple of people get too into their politics or anything like that, it kind of becomes musical chairs at the evening do anyway, because there are a few more people and the assigned seating kind of idea goes a bit out of the window, doesn't it? In theory people will move around, chat, dance and all that, or at least I would hope that they would...
