We will be there Feb 4 and leaving on Feb 15.
The 8th to Thursday, Feb 13 shouldn't be bad at all. There will probably be more crowds on Friday, Feb 14 but still okay. The weekend you leave will be heavier leading into President's day. I noticed previously a real pick up the Saturday morning before Presidents Day.
That week was surprisingly bad last year but it was because Mardi Gras was early so a lot of Louisiana and Mississippi people were there because they had off from school. Mardi Gras isn't until March 4 in 2014.
Have a great time! Hey another SOUTH JERSEY - whoo whoo!
