My family and I (4 people) are arriving at Gatwick airport on 29 Dec 2013, but Gatwick Express is not running during that period because of trackwork. I tried searching alternative trains on Southern and First Capital Connect websites, but the results which came up were around 1 1/2hr journeys. We will be staying at the Thistle Euston hotel and convenience is the key consideration. Should we book a private transfer instead? Any recommendations?
