Weddingbee boards

So I have an old friend who I recently reconnected with on facebook. She lives semi close to me and we keep trying to do a bbq or something at her house with FI & me and her & her hubby. Obvioulsy being so close to the wedding date it hasn't worked out with time etc. I got a message that included this line a few min ago:

The wedding, right around the corner:) Maybe we can stop by and see you on your special day :) Hope you have a great honeymoon, enjoy every minute of it.

Very nice girl and nice message but how do I respond to that? I haven't put our #'s in yet to the venue until this week but I do have the seating chart all worked out to a T. I feel like I should put an invite out there or at least something like:

I would love for you to stop by, we already gave our numbers to the caterer for dinners, however the dancing/drinks/cake will start around 6:30 so feel free to stop by and say hi.

...I have no problem with paying for some drinks and the cake but full out dinner is expensive and I'd have to rearrange seating, which I literally have no room to do.

Bees I need help, what do I do without being rude or offending or making it so we don't talk again?

anybody?

I don't think there is a problem with that. I let my brother do that with some of his friends and it worked out fine. But keep in mind you prob won't have time to see much of them - so hopefully they understand that aspect of it. 

Ok I wanted to check to make sure my response wouldn't be rude! I have no problem with them stopping by and us paying for a few drinks but dinners is totally different and rearranging seating chart is just not gonna happen.
