Anon, thank you so much for breaking down the confirmed people as of now, and the possibles. It really helps to see things more clearly.
I suggest doing what we did last year, set up a whatsapp thread between us so that those more likely to make it can decide between ourselves how to go about the accomodation, prices, etc.
I would say that the thread should be for the ones definitely wanting to come, and for those really trying to come. Then as we make some progress with house choice, etc, we can post it back on here and see if we can get others to join us.
I realize that September seems very far away at this point and it's hard to make definite plans requiring payments, etc. I think it would easily be possible to find extra acomodation later in the year if other people find they can now come.
For those who don't have my whatsapp number already, please pm me.
