The 2005 Open Season is to be extended by one week, due to the high level of corporate interest.
Previously, the last day of the season was to be Sunday, October 30th. Now, the final day of the open season will be Sunday, 6th November.
This is probably a good time to go if you want to beat the queues, as it will almost certainly be very quiet during the last 7 days.
Another Tussauds-owned park, Thorpe Park, has also extended its season by one week.
