The only complication we had was unlocking the lockbox with that 10 digit code they gave us, after that everything was seamless getting in and there was so much to do within walking distance of the place that we had a really great time.
Parking was a nightmare, would definitely recommend parking in the early afternoon and trying to walk to where you want to go if possible. One evening we didn’t get back in until almost midnight and could only find parking some six blocks away.
