Guest communication

Hi! I see some variation has been posted about this, but I thought I’d repost and elaborate a bit more. I’m having a destination wedding where most guests only know a few other people.


Our guests are staying at multiple different hotels and even towns, so it’d be great if there is a way they can write one another. Unfortunately with how popular our wedding weekend is, we weren’t able to secure any shuttles, so I’d like a way for people to say that the car they’re driving has some open seats for example.. maybe a way to suggest things to do after the wedding. Any ideas outside of a Facebook group or mass group text?? I saw WithJoy.com, but It doesn’t totally look like what I’m hoping for. Thank you!!
