Currency Exchange -- There are at least five casas de cambio on Real de Guadalupe, near the main square, and a couple under the colonnade facing the square. Most are open until 8pm, and some are open Sunday.
Doctor -- Try Dr. Roberto Lobato, Av. Belisario Domínguez 17, at Calle Flavio A. Paniagua (tel. 967/678-7777). Don't be unsettled by the fact that his office is next door to Funerales Canober.

Spanish Classes -- The Centro Bilingüe, at the Centro Cultural El Puente, Real de Guadalupe 55, 29250 San Cristóbal de las Casas, Chi. (tel. 800/303-4983 in the U.S., or tel./fax 967/678-3723), offers classes in Spanish and can arrange home stays for their students.
Weather -- San Cristóbal can be chilly when the sun isn't out, especially during the winter. It's 2,100m (7,000 ft.) above sea level. Most hotels are not heated, although some have fireplaces. There is always a possibility of rain, but I would avoid going to San Cristóbal from late August to late October, during the height of the rainy season.
