We are taking an RCCL cruise from Harwich, England in June and have made our own air arrangements to arrive at Gatwick the day before the cruise. We have reservations to stay the night before the cruise in Harwich. RCCL only offers transportation from Gatwick to Harwich if you arrive the day of the sailing, we will need to get to Harwich on our own. Could someone please give us some information as to the easiest and least expensive way of getting from Gatwick to Harwich? Thanks.
