Pack and Plays and Crib Tents/Cross Country Motor Home Trip

Hi Everyone - I'm new here. I have 23 month old boy/girl twins who are
climbing monkeys!

We're going to take a cross country motor home trip in June, and I need
to figure out a safe sleeping arrangment for them. Right now, they are
able to climb out of their cribs, so we added the adaptor to the bed so
they can climb out at any time. We have removed all toys from the room
except soft stuffed animals. They eventually get in one or the other
bed and sleep. In the motor home we will not be able to do this. I
was thinking about putting them in their pack and plays and using crib
tents to keep them contained. Has anyone tried this? Will it work???
Do you have any other suggestions?

Thanks so much!

Debbie
