I?ve parked at Merritt a couple of times. No hangar space, very lax security, and lots of foreign speaking flight training going on. I never had an issue, but last time I was over that way to visit I used space coast. Merritt is right on the water and as a result, your plane will be covered in salt film overnight. Space coast may have short term hangar space. Give them a call. They have lots of parking and good security.
