Semi-Formal. It will be a hot day so I would recommend wearing something light and breezy. It will cool off in the evening so I would recommend checking the weather beforehand to see if you need to bring a light jacket or scarf.
We will have a bus picking everyone up from the Denver Tech Center (DTC). The first bus will take the wedding party up and close family. Then will swing back around to pick up the remaining guests
Just let us know! The venue is very accommodating we just need to give them a bit of time to prepare
Not sure - if you haven't been at high elevation I would recommend drinking lots of water and taking it easy on the wine if you start feeling a bit light-headed.
