hi guys, am planning to travel with my wife to London sometime in October. General questions:a) We were wondering if 9 days is adequate (eg. including 2 days "wasted" travelling to and from London UK to Toronto - net only 7 full days to tour the city). b) We plan to travel early October - this is due to work schedules and all. Is it worth it to travel during those months or will the weather be extremely cold? (I read it's somewhere 5-15C during that time, which is OK but not sure if this is accurate)Just to give you an idea of how we tour cities, when we travelled to San Francisco, 5-6 days is more than enough for us (we stayed primarily in the city for 3 days, one day to napa/sonoma, another day or two in Sacramento! -- the rest such as Muir Woods, Pebble Beach/Monterey, etc - we did that on another 5 day trip). We've never been to the UK so have no basis. When we travel to Hong Kong, 4-5 days is already long enough (we're not from HK either).Many thanks for your suggestions/tips.
