I booked this trip as a solo traveler and had some worries about traveling to TJ. It was nothing but safe and friendly and I’m glad I went. The “snack” was chips and pico, two tacos and some beans and it was very filling. I’m vegetarian so I ate beforehand and I didn’t need to. They made a guac and cheese taco for me special, which was appreciated. I ordered a margarita and it was only $5.00 US. You get 2ish hours to walk around and explore and shop. I was able to bring back some Mexican candies and a bottle of tequila, both of which I paid with credit card so it was super easy. I would recommend this trip, but do not think this is a guided tour, you are on your own when shopping.
