We were lied about a double occupancy room with an extra bed. 3 times we called to assure it would be available and to make sure the rate promised wouldn't change; on the day of arrival the room was not available, the rate to upgrade to a Jr. Suite was more than double what was promised and the overnight desk insisted it was our fault for not writing down the names of the people we spoke to and refused to contact management for assistance.
We ended up at 1:00am walking the streets of Mexico looking for another hotel.
