Not recent, but have used the service there in the past (with 1-3 pax), and no problems ... however a call to EK or Hughes might help. From memory, if you book two cars for two people to the same destination then Hughes may suggest a sinlge car, in which case the onus is on them to make sure its big enough. They did ask whether a luggage trailer was required in the past, by the way, if they thought it might be borderline, but sent the Merc van instead.
