I'm planning a summer Eurotrip with my family (3 adults and 1 kid). The trip starts in Lisbon and ends in Rome. I'm thinking about renting a motorhome in Seville, but I have few concerns.

It will be my first time in Europe and my first time with a motorhome. My concerns are:

Air conditioning at night in summer: how hot will it be?

I am aware of Park4Night, but I am concerned about campsite availability.

I have concerns about security.

Can I park near cities like Barcelona or Saint-Tropez and take a taxi or Uber to visit the city?

I'm considering renting a 7-meter motorhome; is that okay?

This trip will be completed in 10 days.

This is the plan

Am I out of my mind?
