I rented two rooms for July 7, 2017, and arrived admittedly early at 10:30 a.m., wanting to just take the luggage out of the car before driving elsewhere to park. I explained this, and the check-in person said this would be ok. I noticed a sign with the wifi password and asked if I could use this, and he grabbed the sign and turned it around, to keep me from seeing how to access wifi until I checked in. This seemed unhelpful.
There is a long east-west green space between the hotel and the main street, Corso Italia, which is inaccessible, with no paths across it, so one has to walk about six blocks east or west to get around this.
Visitors should know about a large, inexpensive public parking lot just SE off the main square. Parking is also inexpensive at the bottom of the road to Marina Grande - a beautiful place west of the square, and one can park for just 20 euro at the bottom of Marina Picolo, near the center, so it is easy to drive to these places.
I wish I had paid up for the hotels along the water, which is what Sorrento is really about. Other than them, it is a town with lots of noise and fumes from scooters and cars, though a few nice very crowded, narrow, car-less shopping streets.
