I rented an hop on off service for the day. They go very fast. Tons of other drivers and continuous honking which is polite honking so that threw me off I was looking for the accident always. The best part is that you can’t see a thing because of the low ceilings. No worries then. Some of the tourist faces were priceless though. Hanging on for dear life. Not me. No hands except for on my cell phone.
