Went to the DF... there were no naps and a stomach bug

Three days in Mexico City and I got a stomach bug while Miss C just had one 1-hour nap on day two. It was a good visit overall. We stayed at a really nice hotel, Hotel Nikko Mexico. A Japanese/JAL chain. Went to Chapultapec park and then Zocolo the next day. It was short not just because of it being only 3 days but my stomach bug cut the last morning short. We didn't go see the ruins just outside the city. Next time...
