your acclimitizing sounds reasonable to me
1mvertical's experience sounds similar to my Jan98 trip. We took a bus to Amecameca, and managed to not get off. . .we made itback in 2 mins. . And the whole trip to the mountain, on it, and back was smooth. It's a big trail with lots of people! we packed up summit day and hid our stuff under rocks. Our taxi driver even stopped to pick my girlfriend flowers. The taxi was $20 round trip. We also gone done early, so went to the refugio, which was interestingly empty.
It was Very straight forward and fun, not expedition style at all: more like an alpine wknd. Tennis shoes and light crampons is what I'd suggest. The conditions were arid, and there was really no Crevasses on Izta's main route. Thus I wouldn't bring a rope and the like either!! We kept stuff in our hotel whilst up on the MT. If it weren't for the drive/logistics, this could be done as a day trip i think. The logistics are easy. This was my first international trip EVER
, and thus also my first international mountaineering, and I was able to manage it myself, fine.
The altitude gain is the crux.
GO light and make it a tourist thing.
