Whoops. I emailed the hotel to ask if I could cancel. They said ring the booking website, who were very pleasant and cancelled but don't do it again.
Chastened, I found a place that looked appealing over on the Lido, booked it ("free cancellation"), then a couple of days later looked on the map. The Lido is very long and thin, with the boat terminal in the middle. The place I'd booked was miles away. Cancelled.
Now I am set up in an Art Nouveau B&B, bang in the middle, near the boats, the cafes and the beach. Job well done.
My next destination will be Florence for a week. There are hundreds of hotels in Florence. I spent some hours one weekend looking, looking. It always pays to read the reviews. A place might look good; the reviews always have nigglers and whiners.
I've opted for a chain hotel, which is central, looks secure, safe and very bland. Very bland. But I'm hoping I won't be spending too much time in it, an establishment that some former guests - I noticed later - have attacked for having sullen staff, dirty plates in the breakfast area, and hard-as-bones mattresses.
On the other hand, I might keep looking.
Palermo is sorted, with a room on the upper floor of a palazzo run by a very friendly man called Giuseppe. Friends stayed there recently so I know it's all right. They also recommended a B&B in Siracusa - "plain but nice rooms and the very best breakfast in Sicily". I booked that but then I looked it up on Google Maps and saw an amazing place up the road, right on the harbour. A Grand Hotel, no less. So the B&B is out; the Grand in. I may regret that. Why did I forgo the best breakfast in Sicily?
Where to stay in Taormina, on the east coast of Sicily, has always been a given.
I once read an interview with Simple Minds' singer Jim Kerr, who owns a hotel there, Villa Angela. His hotel is not cheap but I got a good rate. It's in an amazing location on the side of a mountain, looking towards Mount Etna.
But hold on. Looking at the photos, the headboard on the bed in one of the rooms is the shape of a huge white scallop and I note that the large TV screens feature Best of Simple Minds DVDs. Aargh. Cheese. I'm sticking with it though. When I leave, I can hum, Don't You Forget About Me.
I bet no one's ever done that before.
