hi guys , we arrive at Tuxtla guttierez airport at about 10.30am on a saturday in november. we'd like to visit the Canyon del sumidero and chiapa de corzo and it makes more sense to do it from Tuxtla but we've already booked 3 nights accommodation in San cristobal de las casas. id it worth doing a seperate half day just for this or do you think it will be possible to do it when we arrive in tuxtla by a tour company (because we will have our luggage) then return to tuxtla and take a bus to San Cristobal afterwards. what do you think? thanks guys!
