* This walking tour will take at least 2 hours, likely more if you plan on stopping to take pictures, read info plaques, or shop along the way. If you plan on hitting Evensong at Westminster, make sure you allow enough time!
* If you want to actually pay to go inside somewhere, make sure you check out admission prices and when they're open. (I recommend checking their websites for the most current and updated information)
* Make sure you take a map with you! I highly recommend having a street map as well as a tube map, just in case. You can get either/both at whatever tube station you start at.
