Travel Tips

Go on the "Jack the Ripper" tour. This tour has a low price, entertaining guides and begins near the Tower of London. This is a great way to end a day of Tower/Tower Bridge tours as there are several good pubs near the start of the tour at Aldgate. Whitechapel still holds that dark and creepy Victorian feel of nocturnal danger and this only adds to the experience. The tube can also take you straight to Aldgate. This tour was a must for me in my travels to London and it went beyond my expectations; very satisfying.

Go To Oxford Street For Shopping. It Is Amazing.
Have a look at the "London Pass" even if you don't buy one you can find a list of places you can visit. There is a link from the page below.
