Going to London this weekend for a load of sightseeing / being tourists. Have accomodation sorted but any recommendations for good stuff to do on a budget much appreciated.
1) Figure that we can do an awful lot just walking around if weather is good, willing to travel so a rough itinerary or spots to see appreciated.
2) If the weather craps out what to do? I know alot of galleries and museums are free but any particular reommendations?
3) Food - Open minded but good quality budget joints wanted. No plans as to where, see points 1 & 2.
4) Nightlife - See point 3.
Neither of us been to London as tourists for ages. Hoping to stay in zone 1 to try and keep things simple. Staying near the City (don't ask) but doesn't really matter as will use tubes / cabs to get back.
Arriving about 1 on Friday, leaving Sunday about 5 (St. Pancras)
Any other advise much appreciated.
