I'm wanting to see the Dyker Heights Christmas lights when I visit in December. I'm staying at the NU hotel in Brooklyn for the first 3 days, so thought it would be best to take a tour from Brooklyn: but the tours I've looked at all start in Union Square - it seems counter-intuitive to go into Manhattan to go back to Brooklyn. Does anyone know if there's a Brooklyn-based tour? Or is it practical to go without a tour by taking public transport and walking around? Or is there a public bus route that goes past?
