Denver: Stay

So I'm going to struggle on this one as we stay with my sister in Stapleton during the summer and pack in to her basement during the winter.  

And while I love Stapleton, parks and pools abound, not to mention the new Stanley, staying in downtown Denver would be a lots of fun as well.  

The RTD, light rail system, in Denver is pretty awesome.  You can easily get from the airport to Union Station and get around the city easily on foot or ubers.
