No! It is completely up to you what you want to do for transportation. Since everything is local, getting around should be relatively easy.
Absolutely. You will be about 6,200 feet higher than you are used to!! Please remember to stay hydrated. Also, note that one beer will feel like two :)
It can be, but Castle Rock is not super mountainous. There are some curvy roads, and there are no reflectors on the roads, so please be mindful when driving at night!
Most of the activities outside of the wedding will be closer to our home in Arvada. The wedding venue is in Castle Rock, 40 minutes away. We suggest looking in Arvada around Olde Town, Westminster, Wheat Ridge, Lakewood or Denver. These are all within 20 minutes of each other! We will be going out in Olde Town Arvada after the rehearsal dinner and spending the day in Golden (15 mins from Arvada) by the river for a brunch picnic the next day.
