Well, this didn't happen at WDW, it happened at a large park here in Canada (in toronto actually) ...Paramount Canada's Wonderland...
my hubby and i, along with 8 or 9 other friends of ours, all spent a weekend in toronto, to 'get away', and this included a day at Wonderland. If anyone happens to be familiar with this place, the event i am about to describe to you happened by the pirate ship area...near the water out in the complete open.
a girl was giving her boyfriend a b.j. right there. they had their back to the pathway where people walk but it was quite obvious what they were doing. they were about 15.
meanwhile, here are ten 26-32 year old adults standing, in a row, mouths open wide in shock! imagine the site, 20 feet away a girl wiping her mouth off and a boy smiling while we are still standing, in a row, shocked. a park rep was walking by and we stopped him and said 'omg look what they are doing' (this was ahem during the incident) and he looked over, his mouth hung open and then he started to laugh....he couldn't believe it! he was going to get supervisor ...hopefully they got kicked out, because really...i mean what if a kid saw it? YIKES!
and yes i swear to God, this is a true story!
