This was so much better than we thought it would be. Quick tip if you are driving park at OldTown at 4015 Twigg Street and try and get there for 9am to 10 pm to maximise the day. Parking here is FREE. Commentary from the drivers was excellent- we jumped off a couple of times and got back on following trolleys. We stopped at Little Italy for lunch and thoroughly recommend doing this - you have a choice of restaurants to suit all budgets and the trolley drop is right in the heart of all the restaurants. We finished the day back at Old Town. A great day and an easy way to see a lot of San Diego- we are from the UK.
