The last two times we've visited (October 2009 and June 2009) the Gardenwalk has had large buses that would pick you up just outside DLR and drive you to the Gardenwalk. I'm hoping this is still the case because this year we're staying at the Residence Inn Maingate (across the street from the Gardenwalk) and it would really be nice if we could ride the buses back to the Gardenwalk after we're finished playing in the parks, have a nice dinner there, and then just walk across the street to our hotel.
