If you visit London you pretty much need to experience how easy it is go get around by going on the Tube. Mind the Gap….I wasn’t sure what that meant until I saw for myself…..there is a gap of space between the platform and the train that you have to be conscious of; otherwise you could trip or hurt yourself…..very easy to get almost anywhere….the trains run continuously and we even took our train from Heathrow right to our hotel at Paddington…..took the esclator directly to the Hilton Hotel and never left the Station…how easy can it get.
