"Also, has anyone in the past crammed two families into one hotel
room?"

YES!!
There were a few of us that did it quietly.
Marji Zintz and I shared a room the first two conferences. It worked
well because she only has one child to my crew of four! So I had one
bed and she and Liam had the other and two of my kids slept on the
floor.
It made the conference affordable for both of us.
