Ken -- great trip reports.
I am about to embark on an (extended) MHD, starting tomorrow, when I leave Aktau and begin a trip that will take me through twelve cities in five countries in thirteen days on five airlines. (My return to LHR starts in CUN and will be straight through CUN-MEX-LAX-YVR-YYC-YYZ-YOW...train to YYZ...YYZ-YUL-LHR, without a night to sleep. Whew!)
Your tips about transiting through MEX will certainly be useful! Sure glad I decided to stay two nights in CUN to (a) rest up from the travel through MEX and (b) to rest up for the travel through MEX. :grin:
