My husband and I are retirees and travel the world full time by pet sitting. It’s affordable (we have confirmed 221 free pet sitting nights so far this year)and fun IF you like travel and pets.. Message me on Instagram if you have any questions about traveling the world by pet sitting: Travelbypetsitting Currently we are back in Spain near Marbella for a month on a lovely pet sit! Then we are heading home after 18 months experiencing our world. I think this fall we may head to Ecuador.
