T2 Long Stay Car Park

Has anyone used the Long Stay at T" before? We booked last year for Premier Car Park but got bumped to Short Stay as they had overbooked, and SS was great right in front of the terminal.
This year we thought we'd use Long Stay as it's closer and I like parking the car myself.
Is it secure enough and are the spaces a decent size (don't want to land to dents in the doors LOL).
Thanks
