Seems to be the case. I took a taxi this morning from HC&R to the corner of Rosado Salas and 45a Avenida. That's in Zone 1. Pretty far out in zone 1 but still in that zone. I handed the cabbie a fifty and a twenty, and was digging for a 5p coin, because it used to be 75 from here to Zone 1, but he looked at me and said, "Es ciento cinquenta." I was a bit surprised. I immediately assumed that the rate had gone up from 75 to 150 but I didn't think to ask him for the new rate card. Also, I was a bit pressed for time. Not sure what the legit rate for 2025.
FYI: the marine park day-use fee has doubled. That's legit. It used to be 109MN last January, and for as long as I can remember. Now it is 217. Per day, per diver. They told me that it just happened on 1 January of this year.
