Hi! I am somewhat new around here as well. My hubby is already living in the Staines area and me and the 3 kiddos (6 1/2, 5 and 2) will be joining him sometime at the end of summer, hopefully.

Of course, I have never been there and don't know all the great neighborhoods, but I might suggest to look into the schools there so that if the 5 year old goes to school soon, you will be a decently close proximity to one.
Just a thought...
Good luck with all the move transitions!
