1. Bags
Anyone who’s been to Disney World in the last few years knows that all guests must go through bag check, before entering the park. Since 9/11, we have become used to this at airports, stadiums, etc. Disney reserves the right NOT to allow any bag, parcel or other item to be brought into the parks, and to deal with any unattended object in such way as they consider appropriate. In addition, some guests (usually random) may be subject to additional screening/security checks at the park entrances.
