1. An interactive entertainment system provided in a venue comprising:
a central audiovisual data reproduction device including a non-transitory computer-readable storage medium, and a processor configured to reproduce audiovisual data in accordance with user inputs;
a plurality of portable interactive entertainment devices operable independently of one another, each of the portable interactive entertainment devices comprises:
a display,
a communication interface configured to wirelessly send and receive data to and from other portable interactive entertainment devices and/or the central audiovisual data reproduction device, and
at least one processor configured to:
cause a user interface to be displayed on the display, and
in response to inputs to the user interface, enable selection of instances of media for playback via the portable interactive entertainment device and/or the central audiovisual data reproduction device:
a transceiver located proximate to entryway/exit of the venue and configured to detect signals emitted by each of the plurality of portable interactive entertainment devices; and
distance determining programmed logic circuitry configured to determine whether a distance between each of the plurality of portable interactive entertainment devices and the entryway/exit of the venue is beyond a predetermined distance,
wherein the plurality of portable interactive entertainment devices are remote interfaces of the central audiovisual data reproduction device, and
each of the plurality of portable interactive entertainment devices comprises:
a security interface configured to periodically send signals to the transceiver located proximate to the entryway/exit of the venue so that the distance determining programmed logic circuitry determines whether the portable interactive entertainment device is within the predetermined distance from the entryway/exit of the venue,
a timer configured to initiate a timing operation in response to determination that the portable interactive entertainment device has moved beyond the predetermined distance from the entryway/exit of the venue, and to continue the timing operation while the device remains beyond the predetermined distance; and
alarm programmed logic circuitry configured to trigger an alarm only when the portable interactive entertainment device remains beyond the predetermined distance from the entryway/exit of the venue for the predetermined amount of time, and increase intensity of the triggered alarm when the distance between the portable interactive entertainment device and the entryway/exit of the venue increases.
