We are back from the trip and had a great time. The kids were awesome. It was work with the baby around, but the great part about camping is that you really don't have anything else to do, so you can enjoy the process.
Here's what we took:
1. His favorite chair from home (vibrating)
2. Pack n Play
3. Stroller
4. Bassinette for sleeping in camper at night
5. Lot's of blankets
We used all the blankets we took and could have used more. We used them for keeping warm and for shade, and as a barrier to keep things clean.
Bassinette worked for sleeping, but next time we'll leave it home and just move the pack n play in the camper for sleeping. Just for one less thing to haul and move around.
We were very happy we took his chair. He likes it at home, and did camping as well. I'm sure it was comforting to have something familiar like that.
The stroller is obvious for camping, who doesn't like to take a walk around the campground.
My advice for anyone with the same concerns I had were to get out and do it.
We are already planning our next camping trip.
