The popularity of a special perk originally slated to end on Aug. 25 has prompted its extension! From now through Dec. 29, 2012, Disney Vacation Club® Members staying at any Disney-owned-and-operated hotel at the Walt Disney World® Resort (whether they booked with vacation points or cash) may enjoy complimentary access to one of the vacation kingdom's most exclusive spaces: the Top of the World Lounge atop Bay Lake Tower at Disney's Contemporary Resort.

Note that Members traveling from other resorts must use Walt Disney World Transportation, as parking will be unavailable to anyone not staying at Bay Lake Tower or Disney's Contemporary Resort. Upon arrival, Members must walk to the Bay Lake Tower main lobby entrance on the ground floor (the typically locked front door will be unlocked during this time, or a Cast Member will be at the door to assist) and check in at the Top of the World Lounge desk in the lobby.

This perk is available exclusively to Members and those in their traveling party who are staying on that Member's reservation. At least one Member in the traveling party must accompany the group and present his or her current Key to the World card displaying a Disney Vacation Club Membership notation in order to gain admission to the lounge. If the Member's Key to the World card doesn't display a Membership notation, a Disney Vacation Club Member ID is required in addition to the Key to the World card to verify Membership
