I have been on 5 WBCCI caravaqns and have 2 more coming up. I have not been on any other caravans. The WBCCI caravans suit me just fine. Very well done, great leaders, low cost. Not a lot of free time on many of them, but enough to see some extra stuff. Suits us fine. Only down side of the WBCCI caravans is that they are long, so you pretty much got to be retired to do them. And WBCCI has not been real coperative with folks who tried setting up short time frame caravans. They have some rules about minimun number of days, etc. If you can, try one.
