Find any last minute shopping needs, or forgot to bring something? Stop by the area for a bite to eat and a stroll around the mall.
If in town a few days before the wedding, and love baseball catch a game of the CO Rockies vs. AZ Diamondbacks. There are also a handful of awesome bars and restaurants in the same area. Troy and I love stopping in at Mexico City Lounge for deep fried tacos before a game. ( only 3 blocks from the front gates) Rock pile tickets are always just a few bucks and have a great view of the field.
Denver offers a handful of wonderful brewery tours down town. Coors is a wonderful one to begin with.
