Dd and I arrived at WDW yesterday mid-morning. We did not hear of last night's tragedy until someone at home asked us about it. This was at lunch time today. Dd and I have been to Animal Kingdom, Kidani Village (Sanaa), and Disney Springs today, as well as around our home resort (SSR). We have noticed nothing different. Security is tighter than last summer but probably about the same as at Christmas. Yesterday, everyone at MK had to go through a metal detector. Today at AK, only a token few were "specially selected" to go through it.
