What to call the rehearsal dinner when you're not actually rehearsing?

We are having a dinner a few nights before our ceremony for the bridal party and close family, but I have no idea what to call it! I've seen this question posted a bunch of times and the suggestions are very cute, but I also have the added problem of not wanting to use the word "wedding".
My husband and I got married at a courthouse almost two years ago because we couldn't afford an actual wedding. Now we can, so we're doing a vow renewal ceremony and reception and having all of those traditional wedding experiences we missed out on the first time. We made a point to not call it a wedding on the invitations because it's technically not. So things like "pre -wedding dinner" or "wedding eve dinner" are super cute, but don't work for us. We're not rehearsing, just giving everyone a chance to actually meet before the big day so I don't want to call it a "rehearsal dinner" and I also don't wasn't it to sound overly formal or stuffy because it's a very laid back event at a pizza parlor.
Can anyone help me out with thinking outside the box and getting a bit creative and cute? My brain is failing me and the best I can come up with is "meet and greet" which even I think is terrible. Help please!!
