Bill Belichick really does take days off ... and by the looks of this pic he snapped of his smokin' hot GF -- he's REALLY enjoying them too!!!
The Patriots head coach took a beach vacay with his long-time GF, Linda Holliday, after the NFL's combine ... and traded in his headset for a camera -- and we're all grateful for it.
Unclear where the two are -- all we know is it's a helluva lot warmer than New England -- but it seems it's been a pretty fun trip for the couple.
