This is a non-negotiable rule for us. We frequently travel with another family, so a party of 10 or so, at one 15 minute restroom stop each per day (by the time you find one, wait in line, return to original spot…), there just went 2.5 hours of the day!
We’d never attempted RD before our trip last January. I insisted. They saw how the lines grew throughout the day, and that by the time that happened, we were pretty much done with the headliners. They are all totally sold on it. There was zero push back when I gave an overview of our upcoming plans.
ETA: We are NOT morning people.
