Bae,
I work out of LGW with BA and yes, there are plenty of commuters. You will find it a lot easier in the winter, as there seems to be more tours than in summer. Additionally, you will work VERY hard in summer as the aircraft utilisation is much higher through these months. You will probably need a room near the airport, but I know guys who commute and only spend 3-5 nights a month in Costa del Crawley.
Hope this helps. Maybe see you at the UK's finest soon...
Mary
