I am an avid review reader and have scoured the trip reports to CRT for the past year. Twice now, I have read where the ceilings have collapsed and there are pictures posted to show as much. The first report was a couple from Germany and the second was just posted recently from California.
I have been to the RM 8 times in the past 10 years and have seen construction going on and realize Mexican standards vs American are different. I am, however, a little concerned... Not so much that I would cancel my October trip but I will be wary of any creaks or groans from the building. Yikes!
