I guess one other option would be to not use synchronization at all, but just move databases.
This may sound stupid, and it would only work if you were basically the only provider so that no one else was using it. And, probably only if you didn't need to out very much.
But, you COULD copy the six databases to your laptop, go out and make your rounds, then come back and paste them back in. The databases would never get corrupted that way.
Again, just throwing that out there.
