Not sure if this is the right forum but I wanted to mention one other thing I noticed when I was in the parks last week.
I saw many more security guards throughout the parks and even saw a K9 unit on more than one occasion. I saw K9 in MK twice, once in Epcot and on the day we were leaving at the Beach Club. The K9 was with his/her partner and walking through the parks. At the resort they were at the front door. I assume this was due to the elevated terror risk but I wondered if there was something more to it. Does anyone know?
