Maybe this is common knowledge...but I didn't see anything about it anywhere prior to our trip. If you are staying on-site, doing online check-in and headed to the park first...there's a good chance you'll have issues entering the park before 10-11am. We had issues at AK yesterday when we got to the gates around 9:30. Ended up waiting in line for Guest relations for 25 minutes to get things resolved. I was told online check-ins don't get processed before 10am so tickets and aren't activated until then. I guess Disney assumes most people are flying in and aren't likely to arrive to parks early...but for our family which flew into Tampa a couple days prior to visit family...then drove over early yesterday, it was obviously an issue. Another CM told me this was something WDW is working to resolve...until then you think they'd put a disclaimer during the online checkin process instead of just the blanket statement saying "you can go directly to the parks." Just a heads up to any other resort guests who may have similar plans.
