Day 4: We’ve pictured The Peninsula Chicago Christmas tree, decorated by Kehoe Designs in classic reds, golds and greens. It sits in the Five-Star hotel’s fifth-floor lobby, which means you can enjoy the famous afternoon tea, Sunday brunch, chocolate bar or a holiday brunch in the presence of the regal tree, all with views of Michigan Avenue through the space’s floor-to-ceiling windows.
