We're soon to be off permanently travelling, with our son, He's 16, and will have 2 years of High School to finish "On the Road" We see lots of fulltimer's blogs and such with little kids, but what...
I would defiantly check into a mifi or using your phone as a hot spot. That is what we do and we have not had any service issues, but then again we do have Verizon. I am not sure about any book or CD options as we have went to an online program for portability. It is called Time4Learning. I really like their new highschool courses ;)
Here is a link to their site- http://www.time4learning.com/homeschool/high_school.html
