Any ideas for cool things to do with a one year old and a five year old?

We want to go to France next year in late August and September. Any recommendations for travel destinations with two small kids 4 and 1. We plan on going by car, so we are flexible.

Did anyone do it recently? The DJI Website claims they do not do it anymore. Is there still a possibility? What would happen if I use the bigger battery or cellular dongle without C1 certification?

I’m looking for any hints on how to go on enjoyable and relaxing vacations with two small children. The kids are 4 and 10months and the four year old is very energetic. Somehow so far everything we tried wasn’t in a way that both parents enjoyed it too much. So we’re happy to learn from your experience. Bonus if it’s not too expensive.

Is anyone around here playing around with TETRA, I pulled a Hytera PTC760 FxB1 radio from the trash at work and learning my way into that technology. if someone has some hints or tips I’d highly appreciate them.
