Mine was today (hi trip buddy!).
I have a group of 7 for half the trip and 3 for the other half, and someone suggested searching for 8 and 4, this was very helpful. I would search for 7 get limited or no times, search for 8 tons of times. Apparently even numbers open up more spots. Not sure how many in your group.
I also got a few error messages on the computer and had more luck on the app, so maybe use both?
