We visited as a day trip from Merida in August 2019. Having come from the southern Mayan sites of Palenque and Calakmul it is hard to believe this is still the same culture because the style and decor are so different. Uxmal is well restored and there was a good photo display in the tiny museum showing before and after pictures of a lot of the site. Very interesting. They continue to work on it, especially around the Governor's Palace, judging by the most recent photos taken in 2012. It's not really as large a site as it looks but we spent a couple hours to see it all. Unfortunately the overpowering stench of guano prevented us from getting too close or inside many of the structures and at 413 pesos foreigner entry fee now (compared to 197 and 111 pesos for Calakmul and Palenque respectively) it is overpriced and feels like a money grab. It is still a very worthy entry on the WHS list nevertheless. Buses weren't frequent enough for us to risk visiting the other sites included in the nomination.
