One of the first things to do when you get to London is go on the Big Bus Sightseeing Tours -it takes you past every famous tourist spot you'll want to see (so you can orient yourself too), you can sit and ride or hop on and off the bus as much as you want, and you also get free passes to ride on river boats, which breaks up the day nicely. They're not 'cheap' but are well worth it for the whole day. Baker Street is one of the places you can get onboard the tour.

The zoo is small and easy to navigate; it's centrally located in the north section of Regent's Park in London-just a short walk away from the Baker Street, Regent's Park and Great Portland Street tube stations.

Marylebone High Street is a great street running north and south from the Euston Road down to Oxford Street in London. The north end is accessed from the Euston road, between Baker street and Regent's Park tube stations-it has character (and you can avoid tourist traps at Baker Street)-sit in the church park amongst the gravestones and have a coffee, visit a pub for lunch or just stay away from Oxford Street and shop in trendy places the locals go.

Do NOT listen to people who say there is a planetarium at Baker Street in London-there used to be but it seems it has closed down ages ago now (Madame Tussauds took it over and expanded)....

Get away from the traffic by Baker Street and head for the cafe in the south side of Regent's Park, a short walk away, where you can enjoy the space and quiet.

Take the kids for a runaround in Regent's Park- the playground is located on the south side of the park, close to Baker Street, Regent's park and Portland Street tube stations.
