We are members of the Royal Palaces pass so this was our motivation for going. After checking the opening times and spending the money getting there their was s sign saying it was closed for the day as it was rented out for a function! This was at the end of our trip and we had no time to go back so didn't get in. Their info pamplet should say to ring and check it is open! The pass was worth it but Kensington was under renovation, Kew very dissapointing and this was closed, Hampton court and the Tower of London were great. The pass is marginal for tourists like ourselves even though we had 5 weeks to use it.
