The Palace itself was beautiful, though much smaller than I expected. The Palace has only been opened to the public for a few years, and only for a short season each year -- well worth a look, in case the royal family decides they want to stop these excursions through their London home.
I would never use Evans Evans tours again. We pre-booked this tour prior to leaving home, with the understanding that you had to pre-book Buckingham Palace; otherwise, you would not get in. It cost $98 per person for what was advertised as a three-hour tour, finishing at lunch time at the palace. When I received our Great Britain Heritage Cards, booked after the Evans Evans Tour, I found we could have gotten in for free with these but may have had to wait up to two hours for entry, depending on the queues.
Not having to wait in the queue was the only good thing I have to say about how the tour was operated. We made our way to the pick-up point at about 8am, and the tour was scheduled to start at 9am. The bus took us a whole 10 minutes away to Victoria Bus Station, where we were transferred to a larger coach and sat in the depot til nearly 10am. We then were taken on a tour of the city with a guide who had the most annoying voice and mannerisms and did not do as good a job as the much cheaper hop-on-hop-off buses of the day before. We were taken to the Albert Memorial and the Victoria and Albert (but not allowed in), and we were taken to Kensington Palace and walked through the park and stood at the fence for ages (but again, were not allowed in) and then dumped at Westminster Abbey to purchase a cup of tea (again, with strict instructions to not go in, as the guide didn’t want to have any trouble rounding anyone up). All these sites were open to the public and had virtually no queues at the time we visited.
We were then dumped at Buckingham Palace at noon (nearly lunchtime), the time the tour had been advertised to finish, as the guide said to "do the palace and the gardens on your own." In truth, we would have been better off just going and waiting at the palace queue early in the morning or with the tour taking us to one of the places mentioned and letting us go in and do it properly; it just felt as if they were wasting time till they could throw us at the Buckingham Palace staff. Consequently, we had to fly through the palace, as we had booked a hire car at 1pm to drive to the South of England that afternoon. I still don’t know what we actually paid the bus tour for, as they did virtually nothing and even had the hide to made sounds like they should receive a tip!
Read the brochures carefully before booking trips, and try to confirm the information that appears to be there and that you are getting what you think. Our brochure said that the tour ends at the palace at noon, where you are free to continue exploring the gardens; that really meant that, once you were passed to the BP staff, the whole tour, not just the gardens, was on your own. We actually missed the gardens, as the car company would only extend our pick-up time by an hour, and we had to be in Lymington to book into our timeshare by 5pm. There were a number of groups on the bus from Australia who felt they had been mislead and, like us, were scrambling to try and change the arrangements they had made for the afternoon when we made stops.
Having had my whine –- the hand-over to palace staff was extremely smooth, and the organisation of that staff saw us very promptly guided through their various entry protocols without having to sit and wait for admission. We were travelling in September and were near the end of the palace’s opening season. If you were travelling in the peak season, the ability to just walk straight in on delivery would be an advantage, so one may use a tour company to gain access. Just read the fine print carefully so that you know what to expect.
