I'll be in London for the first time with a friend (we are both in our early thirties) this coming September, and I have sort of an itinerary planned (but keeping it flexible at the same time). I've just got a couple of questions to ask:-
1) Our flight will be arriving in Heathrow at 9.10am. Assuming I'll take at least an hour to go through immigration (as I'm a non-EU citizen), by the time we are ready to go to the hotel, it'd probably be around 10am. We are planning to take the tube to King's Cross (our hotel will be Pullman St Pancras), and I'll be carrying a 34ltr backpack and a four-wheeler as well. Will the tube still be crazily squeezy around that time when the train goes into Central London? Will my backpack be in the way of commuters? (I can carry it in front of me.) I won't be bringing that backpack during the days of sightseeing, that's for sure (although I wish I could), but I didn't want to create any inconvenience to locals travelling on the tube during my day of arrival either.
2) Assuming we are able to check in or at least leave our bags at the hotel by 12 noon, I was thinking of going straight to Old Spitalfields Market (I purposely chose Thursday to arrive in London as I was thinking of picking up a gift for my friend's mother, who loves antiques and strange knick-knacks). But I am also interested in Camden Market as well. As Old Spitalfields Market closes at 5pm and Camden closes at 6pm, is it possible to actually visit both on the same day? Or would it be way too rushed? If there's only time for one market out of these two, which one would you recommend?
3) Our departure day is on a Monday, and the flight is at 10am in the morning. We are planning to check out at 6.30am to leave for the airport, and I was thinking of taking the tube again, but my friend is a little apprehensive about it as he worries about the Tube breaking down or having delays, or that it'll be too squeezy to board the Tube, etc, and that we'll be late in catching our flight. Are his worries unfounded? Or would it really be better for us to book for an airport transfer instead? Do I need to worry about traffic jams on the road from King's Cross to Heathrow at 7~8am in the morning? Or should I leave earlier for the airport?
