Hello - I will be arriving in London on August 11th at around 10:00 am staying at the Hilton London Metropole to pick up a Globus Coach Tour leaving the next morning (Sunday August 12th) coming back into London on Tuesday August 21 around 4:00 pm staying at the London Hyde Park Hotel. Globus is offering an optional excursion of seeing Wicked on the Tuesday evening with a 3-course dinner for GBP 99 (transportation to and from the hotel) . Since I am not a big dinner person, it is easy to get a great single seat on either the Saturday August 11th or Tuesday August 21st for a better price. Would I be better to book in advance on line and how challenging is it to get from the hotel to the theatre offering Wicked. Any recommendations would be greatly appreciated. Thank you.
