Continuity mistake: As mentioned in a previous error, just before Jake is checked into the Surf Hotel, there is a long scrolling shot that illustrates the surroundings of Jake's room in the hotel. In particular, notice that Nathan's Seafood and Clam Bar is not across the street from Kennedy Fried Chicken. This is contradicted later when a) Jake looks out of his window and sees the Nathan's sign, and b) Jake is seen leaning out of his window above the Kennedy sign.
Continuity mistake: When the two officers escort Jake into his hotel room, you can see that there is a wall to the right of the three men as they walk into the room. In other words, Jake's room is at the end of a hallway. However, when the officers leave Jake's room, you can hear the door shut, and the wall is no longer there. In other words, Jake's room is no longer at the end of a hallway.
Revealing mistake: Just before Jake is checked into the Surf Hotel, there is a long scrolling shot following the car and shows where Jake's room will be. In particular, there is the Kennedy Fried Chicken sign with one window above 'Chick' and one above the 'K'. After checking into the hotel and the guards leave, we see Jake outside of his window. This shot involves a recreation of the original location because the two windows are now above the 'nnedy' and 'en'. Furthermore, the lights surrounding the sign have changed (some are burnt out or missing, and they don't flash at the same time interval).
