🎉 Help me throw a party! 🎉

Hi, folks.

On February 18 next year, I'll host my 60th birthday party. 🎉🎉🎉. I'm looking for ideas.

I'm going to cater it, but don't know what to get. My criteria:
Nothing super messy (i.e. spaghetti, Chinese)
No "make your own" (i.e. sandwiches, tacos)
Must be easy to eat from/with disposable plates and utensils.
What would you think about ready-made sandwiches and snacks from a place I know that makes kick-ass sandwiches?*

I'm also hoping for suggestions about the party itself - although I have no idea of what I'm asking for. Here's what I'm working with:

The party will be in my house, which has a normal-size living room with seating for 8-10 (cramped), a decently-sized dining room in which we seated 15 for Thanksgiving last year, and a tiny kitchen.**

So, alas, no Twister. 😕

We can use the covered patio for overflow or for just standing-around-talking room, if the weather's not cold and wet. We can seat nine out there. We could also use it as the staging area for the food (again, weather permitting).

My guest list is currently at 24, including two people from Oregon and three from Missouri. That's a lot of people for this little house. There's no way that everyone could sit down at once. I may have to cull the list.

*Corner Bakery, for those of you in the know.
**The tarot reader will be in the guest room. 😁
