02/01/13. -  This morning we caught the tube to Oxford Circus where we changed and went to Green Park and Buckingham Palace to see the changing of the Guard. We had missed it last time as it was raining. There were thousands of people there but I managed eventually to get a place at the fence where I could see what was happening. We had lunch in the park and it was on the Tube again to Leicester Square where we hoped to get cheap tickets to a show tonight. We did, and Mason and I are off to see "Wicked" at 7.30pm.  On to Knightsbridge and a walk through Harrods. Interesting, as were the prices!!  The underground is amazing and really good to get around London once you have sussed it out. Not good with luggage though! We left Alice and Glen who wanted to grab a bus for a further look around the city while we came back to the hotel to rest before venturing out again this evening.  Got some prices to take a taxi to the bus station tomorrow (£30 as opposed to £20 on the Tube) Will talk about it tonight but think the extra will be worth it -less stress.
