You tour on your own pace and they have people inside who answer question and give info on the house and rooms. The house closes at 5:15pm
The tours are self-guided, so you don't need to come for a specific tour time. Last entry is at 5:15 from Apr 15-Oct 31 or at 4:15 from Nov 1-Apr. The Visitor Center (with exhibits, shop, and restrooms) closes 15 minutes earlier. Make sure you arrive before then to see the display of Revere-made silver. If you arrive near closing time, you can still see the Revere House itself, but if you like to read everything you might feel rushed.
They're open April 15 - October 31: 9:30 am to 5:15 pm and November 1 - April 14: 9:30 am to 4:15 pm. The average visit is around 30 minutes but thay might change depending on group size and/or how busy it is (wasn't busy when I was there.)
