If your residence, permanent address, is point A and just going to point B for a couple of months, a mail forwarding service is not necessary and a waste of money. Our long term, mid Oct to end of May, residence is Yuma. The rest of the time, including a couple of weeks going and coming, is spent at one location in Washington. USPS forwards our mail and will do this for as long as 6 months without changing our permanent address from Yuma. Private mail forwarding services, such as Escapees, is necessary when you travel to many places throughout the year, staying at one location for a couple of days or a couple of weeks then moving on to a new location.
