My husband and I (and hopefully, our two adult children) will be visiting the Denver area the first week of July, 2012. Our nephew and his family live in Castle Rock. I am trying to find a location that will be centrally located between the Denver airport (in case we are picking up/dropping off adult children mid-stay), my nephew in Castle Rock and the places that we would like to visit in the area (Pike's Peak, Rocky Mountain National Park and other places that I still have to research). We would like to rent a condo, cabin or home for the week. Does anyone have any suggestions?
