Have you used the San Diego Go Card?

[Duffy Lover]

We just booked a sweet little Airbnb in San Diego for our spring break! Yay! I'm considering getting us a San Diego Go Card and I'm looking for general info from folks who've actually used it... We'd either get the 3-day version or the 4-day Costco version for only $15 more per person.

So have you used it? Easy?

Has anyone used the Costco version?

Suggestions or tips?

TIA!!
