I just heard about this today.
Welcome to H.E.L.M. Travel
Bring Joy to Learning.Want to travel with the kids but can't afford all the expenses?What if you could "switch" homes with another homeschooling family and therefore, save on accommodations?H.E.L.M. Travel is organizing a pool of homeschooling families who are looking to enrich their children’s education through hands-on learning experiences. You and other homeschooling families will exchange their primary residence, a second/vacation home, maybe even a timeshare that isn’t being used OR you can choose to host a family in your home rather than exchanging during one, two or three pre-designated dates.
