We ahve been here since Sunday: generally what NCC1701Q (no bloody A, B, C, or D?

) said is correct.
We did notice, and comment to ourselves today, that there is more uniformed security personnel out and about today and that there were several with dogs both in the parks (we saw one in each park) and in the "between" area (saw 2 in the area between parks and top of Disney Village). We are staying onsite and walking so do not know how much might have been added near the RER station.
It really is not slowing anythign down--but I do get the impression they are keeping a close eye out -- especially with all the dogs.
