Peach,
If you won't have a car and don't want to live in Crawley, why don't you look for somewhere in Croydon?
There are quite a few crew living here, however you never feel as if your surrounded by them, as you will in places like Crawley and Horley etc.
I've lived here for the last 4yrs and have never had a problem getting to work.
The train to LGW runs 24hrs a day,and the trains leave about every 15mins during the day and about every 30mins during the nite and the journey time is about 15/20mins.
It is also very handy for central London with trains going all day and nite. The journey time to Clapham Junction is about 10mins and then about another 5mins to Victoria.
Croydon also had a wide range of bars,cafes,and restaurants & shops with someting to suit almost all tastes.
Hope this is of some help...
