We are starting to plan a 6 week summer road trip for 2018. Our starting/ending point is LA. And we will have a 5 yr old and almost 3 year old. This will be our first time doing a camping road trip. We plan to tent camp and occasional motel. We'd like our kids to see nature and just create family memories. We have friends in Austin, TX we'd like to see and I'd like to go to Yellowstone, but prefer to stay at a cabin inside the park. I also would love to go to Charleston or Savannah, but think that might be too far. Just found out that reservations have already in opened Yellowstone for next summer-so we might be a little behind in planning.
Since we have little kids, we want a relaxed/slower paced road trip with maybe staying a couple to few nights in most spots. Our kids tend to do well in the car, but definitely need suggestions for stops to stretch the legs/burn off some energy. Since we can more easily see CA sites, we're mostly interested in recommendations outside of CA. Do people have recommendations for sites to see or good campgrounds for little kids (ones with playgrounds)? Recommended routes? How long of a time should we plan at Yellowstone and where should we stay?
Thank you so much!
