While planning our trip to London, Warner Bros Studio was a must-do! We are fans of Jk Rowling. My daughter is obsessed, me not so much, but it was entertaining. We used Viator previously in Italy and USA, They have been reliable and customer service oriented. This tour makes you call..not email, which was difficult without international plan. Hotel concierge helped us out. Bus ride did not provide wifi even though advertised as a feature, no film or music, Literally our guide slept until minutes before we arrived at Studio. we were left on bus while guide purchased tickets and only then were we given pickup instructions. Nice comfortable bus, prompt arrival and return, sufficient time allowed. Recommend....as easy transport to see Warner Bros.
