"Chill out time" and "beach time" are in fact very different, since beach time can actually be somewhat taxing. I mean, having to apply sunscreen every hour or so, walking from the lounge chair to the water to take a dip in the 90 degree water, and reading your book under a nice shady umbrella are all kind of strenusous. Thus, the importance of "chill out" time to do absolutely nothing but stare off into the sunset is crucial!
