Thanks for all the replies so far I am really grateful.

I have looked at cycle carriers that attach to the rear window (and
indeed am going to try one next week. but most only go as far as 3
bikes and we really want to carry 4.

just remember to keep the noseweight of the trailer plus the weight of
the 4 bikes and the carrier below the limits set by either the car
manufacturer or the tow bar manufacturer (whichever is the lower)

And there lies the problem. 4 bikes is 50kg to start with, which leaves
nothing for the trailer on many.
