I have looked all over for reasonably priced hotels to stay the night before in Gatwick and last year we used this one.Its called the Four Seasons and for a triple room and 14 days parking cost us £105.00. The owners run you in to the airport and you get a taxi back, about a fiver. Excellent breakfast and good welcome. They were so good we are going back this year and prices are still the same.
