Given that its February and its winter season, wear boots. Not high heeled boots (madulas kasi sya) but those that are rubber and have got good grip and are either leather or plastic. Not the nice Ugg boots na pag umulan basa na din ang paa mo hehe. Check accuweather, a few weeks ago it snowed in London ( Feb -.April 2012 was the last time it snowed in London), 4 seasons in one day weather talaga sya. There might not be snow, but it will probably about 90% chance na uulan sya. By the way, download TFL.and the London Underground App. It will make it easier for you to commute. Also update your google maps app, back up kung hindi mo mahanap kung saan yung mga rail and underground stations. 4 PM pa lang madilim na sa London. By bus, Maidenhead to London might take a few hours. By train, about 1-2 hours siguro give or take no delays. Tfl app is only good for London. Google maps is better for countryside, which Maidenhead is.
If you only have 9-5 pm, okay na yung itinerary mo. Greenwich park is also nice ( venue of the movie Thor hehe) but it's better in spring and summer, plus mauulan baka maputik. Magkakalapit lang ang London bridge, tower bridge and St. Paul's Cathedral. If you want to go to westminister abbey or to the London Eye, you can take the ferry or city cruise. If you're lucky and the weather is good, yung steward ng city cruise will be your tourist guide and point out all the important landmarks and give out trivia. (Of course you can also take the underground train). From London Eye you can check out the waterloo station ( where you'll probably catch your train back to Maidenhead).
From Waterloo station, you can walk to London Eye, cross the Westminster bridge, see the Parliament upclose and check out Big Ben. And from there you can walk to Westminster Abbey and konting kembot na lang you can walk to St. James Park, see the Buckingham Palace, walk some more till you see Victoria Station and you can also walk to Westminster Cathedral ( Catholic Church).
Now, if you want to see more people, and maybe check out more sites and not go into St. James Park, from Westminster Abbey, you can walk along the side of Thames river opposite London Eye, until you get to Charing Cross Station, from there you can walk to Trafalgar Square, see the National Portrait Gallery, the National Gallery, Leicester Square ( if you're going back to Heathrow then this would be your station ), Chinatown and Covent Garden.
If you want cheap eats, there is Wasabi which is a Japanese bento stall/ resto. You can try Nando's Peri-Peri Chicken not sure kung wala pa nyan sa Pinas, since.meron na dyang Costa's eh). For typical English food, try any pub hehe.. but Punch and Judy makes good sausage and mash
Anyways, mahaba na pala ito. Good luck. Bu the way, there is this escalator etiquette, otherwise you might get told off, remember you stand on the right and walk on the left. Good luck. Have a great work holiday
