A slowish start - out the door by 10:30 - no reason - just lethargy and of course social media demands of certain tourists! We caught a bus right outside the hotel door after figuring out that the shop 20 metres down the road sold the tickets. Five quid each for buses and trams all day (never saw any trams though!). We caught the bus to Trafalgar Square and went to wander down 'The Mall' (Pall Mall) when we saw a crowd gathered in front of what turned out to be the Household Cavalry's stables but now is their museum. There was no changing of the guard today at Buckingham Palace so we were lucky to stumble across this which was one troop coming from nearby Hyde Park quarters replacing the ones going back. Beautiful horses and dashing Calvary soldiers ! We then walked down to the palace itself through St James Park then walked back to the St James Cafe which was such a nice place to eat we returned later for a late lunch! We then walked around past Downing Street (blocked off) and over London Bridge and went on the London Eye. Ticked that box and then went back for a stroll past Parliament, through the grounds of Westminster School and then headed back to St James Park where we saw the pelicans (yes pelicans) being fed before lunch at the cafe. Somehow we then had the bright idea of going to Notting Hill. Anyway the bus trip through town Regent Street, Oxford Street, Edgeware Road etc took forever. We got there, walked around a few streets and then caught the tube back to Oxford Street to see Marks & Spencers. We then went on a wild goose chase looking for some luggage scales at what turned out to be an online store - so you could buy them but would have to wait a week to get them! We had some trouble then finding how to get back by bus (because the tube was so bloody expensive and we had bus tickets anyway). The bus system is so complicated it took us a while to figure out which street we needed to get onto to catch buses going in the right direction, but once that was sorted we were honky-dory. We got back to the hotel around 8pm, still incredulous at the number of after-work drinkers still milling around outside all the pubs - but believe it not there were still heaps of them still there when we went across the road to The Chamberlain Pub at 9pm - talk about a drinking culture! We had a reasonable meal there and retired for the night as we have an early start tomorrow, going on a full-day trip to the Cotswolds.
