My kids are in APL since 2 years, they love the school and we are happy with the progress too. The staff and management are very supportive and child-centred. At least that is our experience so far and i havent heard otherwise. I'am not sure about extra curricular activities for KG, but the rest of the school does have activities part of their daily routine. they have additional club activities too. You can go through their website for more details or speak to one of their staff for better idea. they will definitely respond.
sorry regarding your query on transport, depends on which area you are and if there are other parents who send their kids to APL you could discuss with them to find a better option. some people these days opt for car pooling along with their neighbours. parents take turn to pick and drop kids.
also attend the orientation program if they have given the dates to you, it sheds alot of light and you also get to meet the mentor and other parents.
