Yeah, unfortunately they have daily meeting on this forum. ????
However, as you have found out, you have a lot of options.
1. Just apply and get the day they tell you.
2. Apply on Friday, and get on Monday
3. Travel first, where you wish to go, and later go to Savannakhet or Vientiane to take care of visa before entering Thailand again.
Just to take your pick and be happy happy.
