Thank you for using Upcoming! To help focus our efforts on core Yahoo! product experiences, we will discontinue Upcoming by 30th April 2013. You can find more details here
Tours take place daily at 9:30 am, 11:30 am, 1 pm and 3 pm. We have created an entire "National Treasure Tour" where visitors can take an hour-long walking tour that includes behind-the-scenes information. These popular tours sell out quickly so please plan ahead! Purchasing tickets online is recommended.
