Pro tip: if you book online instead of purchasing your tix at one of the kiosks, you save a few $. You can also save $ on some of the additional sights at some of the trolley stops, such as the Maritime Museum (fabulous). Ditto for some of the venues in Balboa Park (another stop) such as the San Diego Zoo and the art museum (another pro tip: if you are a member of an art museum in your home city, check your membership level: it may entitle you to reciprocity/free or discounted entry at certain art museums in other cities; so before you buy a ticket to the SD art museum discounted through the Trolley Tours, check your own art museum’s member card: you might already qualify to get in free!). The San Diego trolley tour is one of the best values in the city. There is much to see at nearly every stop and you can hop on and hop off as many times as you like and return to the stop where you got off and wait for the next trolley to come along (they come by every 20 minutes or so). the only drawback is that San Diego has such a wealth of things to see and do that you need to spend a few days on the trolley because they really only run 9-5. I found myself spending a few hours at the Zoo, or at 1 museum, then add in time for meals, and getting back around the circuit to where you first boarded (presumably near your hotel) and there goes the day. You need at least 1 day (maybe 2) just for all the incredible sights in Balboa Park (MANY museums, plus the Zoo, plus several gardens and the Old Globe theatre; — and it’s just so beautiful and lush); you could spend at least a half-day in Old Town (another stop), and at least 2.5 hours at the Maritime Museum and/or the Midway aircraft carrier (another stop). Leave plenty of time for Coronado (if you aren’t already staying there). You will find that in the course of several hop-on’s and offs that you’ll experience several driver-guides. Some are better than others. And even though the tour is scripted, with various points where the driver will press a button for a musical cue, some drivers are just natural raconteurs and have a terrific ease with the passengers. Others have just memorized the script and are not adding much personal oomph to it. The drivers who have a personal connection to some of the items of interest on the tour are the stronger ones. A couple of the older guys (there seem to be a lot of military veterans) — Jack and Hatch—in particular were excellent. But another driver just told silly one-liners in lieu of providing meaningful historical background and context to the script. After 3 days I was finding it interesting to hear what some drivers left out, and what others had either embellished or where the “facts” differed from info their colleagues had provided. In any case, several of the drivers seem to be passionate about guiding visitors to San Diego and the Trolley Tour is one of the best values in the city if you use it to really explore every stop.
