This is our first 4th of July week at poly so I don't know if its normal but they've roped out an area on the beach with chairs for CL guests only. I'm pleased with this, I think, cause we couldn't see the water parade at all from our patio last night due to all the people, so we may go in the reserved area.
Also, there are signs in the lounge expressing it's for CL guests only, and a CM has been asking to see room keys. I talked to a CM about this and she said they have a huge problem with people sneaking in, especially at holidays.
I've also heard rumor they will deviate from the normal menu and have traditional 4th of July food. I'll know for sure soon enough!
