lots of hotels around gatwick let you park for free if you stay 1 night with them , surely taht be less than 140 quid and save driving same day as flight
may be worth posting in misc to see if anyone lives local and will let you park outside
and get a taxi the rest of the way
I would for a beer is i was local
Sorry just checked your actual dates and these are more expensive . I used to park along a residential street in Crawley. Virtually the whole street was in on it. The street in Benhams Drive but i have lost all the phone numbers i'm afraid. Shame as they only charged £10 per week 3 or 4 years ago.
