What about the idea of a loop and then in the future having LRT spokes coming off? For example, the loop would go around the SW side of downtown and people could get off at stop at NW corner of the new park, get on a LRT down to the airport? The LRT would be fast and need less stops, but still provide access to fun destinations like Stockyards at the couple/few stops it has on the way to the airport. I think this idea (streetcar loop - LRT spokes) would be a good mix and allow future connections/expansion.
