Did that with my group of friends for South Korea.
One day 30k steps for 14 days non-stop. Some days can do 45k.

Instant blacklist in my travel buddies. No more.

These days I only do chill trip with another group. Much better.
Wake up 9.30am, go cafe breakfast, then 11am drive and eat some nice lunch, sightseeing, 6pm dinner, then chill at cafe. 8pm onward free and easy.
