Should i have a table for the wedding party?

If you aren't serving a meal, I would avoid doing any assigned seating. It's rude to chose for some and not everyone. Also, the sweat heart table seems random, why are you going to be sitting, just the two of you, as all your guests stand and mingle?

I assume some guests would be sitting but it would be kind of weird to sit by yourselves while people are not formally sitting, as in everyone not sitting all at the same time. Most people say you barely even get to eat or sit at your own wedding and that's when there is an actual meal served, so just seems unlikely and would look odd that you are off sitting on your own whilst so many are mingling...why would everyone sit down at the same time or necessarily all if they are just eating appetizers?

Hmmmm I see, you will have a buffet. That definitely means more people will sit and probably a big bulk once the buffet opens. That would make the sweetheart table not stand out as much but then there is that pressure of who to sit with. I think since you are having food that will require people to sit, you can do the sweet heart table and in reality you probably wont sit there long but it allows you to actually make sure to eat something and have a moment together.

My BILs did something similar at their wedding, they had a sweetheart table that was decorated a bit more than the other tables and open seating for everyone else (they had a food truck catering so things were pretty laid back structure-wise). They sat at their table during the speeches, etc and it worked out great! With the more laid-back vibe the unassigned seating was perfect, it was nice they had a specific spot for themselves (even if they weren't sitting there for too much of the night) but it definitely wasn't necessary to reserve spots for anyone else as everyone moved around so much.
