Our first caravan was with Tracks to Adventure (since absorbed by Adventure Caravans) to the Maritimes and Labrador and Newfoundland. We have since traveled several times on long trips to the Copper Canyon, Guadalajara and Baja, Mexico with Adventure Caravans. We would not have ventured so far into Mexico on our own but we have gone as far as La Bufadora and Puerto Penasco solo. We are scheduled again with Adventure Caravans to Florida/Georgia/Carolinas in February.
For us their planning, routing, access to little known venues, charter bus day trips, ferry and campground reservations, group meals (restaurants and our own pot lucks), companionship of like minded rv'ers and mechanical breakdown support are valuable. This is most important when we wish to tour on the East Coast with which we are unfamiliar. We want to see "all there is to see" after we travel cross country to meet the caravan. Yes, I know, we never will see it all.
We would not sign up for a caravan in the more familiar western states or provinces, except possibly to Alaska. And, at the end of being with a group of up to 42 others ( 38 persons = 18 rigs + 4 staff = 2 rigs + us) for a month or longer, we are ready to head off by ourselves again.
Some people travel extensively with caravans. Others never do.
Alaska Treks advertises smaller groups. We have not traveled with them or Fantasy RV Tours but they both also offer some interesting trips.
To caravan is a obviously a personal value/benefit decision. The factors are probably a little different for everyone.
Disclaimer: We don't work for, or have any financial interest, in any caravan company. We are just satisfied customers who have found that they fit our plans under certain circumstances.
Have fun. Drive safely.
