Basically because they contract to a certain UK holiday company that company puts clauses in the contract to prevent them selling rooms to UK customers direct quite naughty and I don't know how far you would get using as foreign travel firm for the room once it was found out you have a UK adresss
We asked while we were there at CSR. They are bound in contract with FC for 10yrs to all UK. So no direct booking I'm afraid. I wish FC would sort the entertainment out though. Don't think either we would book through these again.
