This was an amazing experience! The past reviews are definitely accurate. I was most worried about the meeting point as they gave us the address to McDonald’s on the US side. Just know that they will text you right before to meet on the Mexican side of the border. It was very easy to walk over from the McDonald’s address, so rest assured you will make it to the right place. Once you go through the border, keep walking until you go through a white swinging gate where there is a food stand and vendors. They will be waiting for you! The experience itself was great. We did the 4 hour tour - I wished we had more time for shopping, so maybe we will do the 6 hour next time (only 30 mins for this one). We felt extremely safe. Gregorio and Tadeo were very knowledgeable and fun! I would do this again!
