The term 'REST SPOT' can be broken down into two crossword solutions: SPA (3 letters) and COT (3 letters). A SPA is a place where people go to relax and rejuvenate, often involving treatments such as massages, facials, and other body treatments. A COT is a type of bed, usually smaller than a regular bed, that is used for camping or in emergency situations. Therefore, a rest spot could be a SPA or a COT, both of which provide a place to relax and rest.
