8pm should be fine. Park st (at the common) does tend to attract a certain group of people that hang in the area, but they don’t really bother anyone.

Omni Parker house is very close to the Orpheum, if you want a place that’s quick to get to. The Godfrey as well. XV beacon is just a little bit further of a walk, but close.

The area is pretty saturated with hotels, it depends on how far you’re willing to walk. If you want to walk the least then omni or Godfrey would be the best options
