The information presented by the quote and JSTOR is accurate, at least insofar as it reveals that a significant number of individuals in USSR went on either tourist tours or sanatoria each year for rejuvenation.
In the 90s, state sanatoria maintained their popularity in post-Soviet countries. To this day, travel agencies in some of these nations primarily focus on two types of journeys: relaxation and "learning" holidays. This deeply ingrained cultural practice persists throughout the region.
I don't know how many and which groups of people went on annual holidays in the USSR, but I know it wasn't an insignificant number from what I've observed living there as a kid.
