There’s now a parador turística–a glorified highway pull-off—near Becal where you can buy all sorts of panama hats. Most are in the semi-decent souvenir category, though.
The sound-and-light show (p. 276) now costs M$40 and starts at 8.30pm. It also costs M$10 to go up in the Puerta de Tierra during the day, and there’s a small museum there now.
The Museo de las Estelas (p. 276) has been renamed the Museo de la Escultura Maya, and has English labeling.
Mansión Carvajal (p. 275) has reopened—you can visit between 8am and 2pm Mon–Fri.
Fuerte de San José (p. 277) has reopened.
It’s not stated explicitly in the text, but note that no city museums are open on Monday, so plan accordingly.
Jardín Botánico Xmuch’haltún (p. 276) is closed.
